A Case of Extensive Multifocal Tuberculosis Verrucosa Cutis

Tuberculosis is probably as old as the human race itself. Cutaneous tuberculosis constitutes a very small proportion of extra pulmonary tuberculosis. Extensive, multifocal involvement of cutaneous tuberculosis is a very rare manifestation. We report one such case of extensive, multifocal tuberculosis verrucosa cutis in a 30-year-old immunocompetent male patient in the absence of any primary tubercular focus.     

A clinical and histopathological profile of patients with cutaneous tuberculosis

Extrapulmonary tuberculosis constitutes about 10% of all cases of tuberculosis, and cutaneous tuberculosis makes up only a small proportion of these cases. Despite prevention programs, tuberculosis is still progressing endemically in developing countries. Commonest clinical variant of cutaneous tuberculosis in our study was lupus vulgaris seen in 55% patients followed by scrufuloderma seen in 25% patients followed by orificial tuberculosis, tuberculosis verrucosa cutis, papulonecrotic tuberculid, and erythema induratum seen in 5% each. The commonest site of involvement was limbs seen in 50% patients followed by neck seen in 25% patients, face in 15%, and trunk in 10% patients. Maximum percentage of patients (55%) had duration of cutaneous tuberculosis between 6-12 months followed by 35% between 13-24 months, 5% had duration of cutaneous tuberculosis less than 6 months, and the rest 5% had duration more than 24 months. The commonest histopathological feature in our study was tuberculoid granuloma with epitheloid cell and Langhans giant cells seen in 70% patients, hyperkeratosis was seen in 15% patients and AFB bacilli were seen in 5% patients.     

ELEPHANTIASIS OF THE EXTERNAL GENITALIA: A SEQUEL TO CUTANEOUS TUBERCULOSIS

Tuberculosis continues to be an important public health problem and cutaneous tuberculosis constitutes a minor proportion of extra pulmonary manifestations of tuberculosis. Elephantiasis of the external genitalia, as a sequel to cutaneous tuberculosis, in a 40-year-old diabetic lady is being reported for its rarity. The patient also had lesions of healed scrofuloderma of 27 years’ duration, in both axillae, with residual pedunculated nodules.     

A clinicopathological study of cutaneous tuberculosis at Dibrugarh district, Assam

Background:

Cutaneous tuberculosis forms a small subset of extra pulmonary tuberculosis and has a worldwide distribution.

Aims:

The present study is an attempt to find out the incidence, clinical spectrum, and histopathological features of cutaneous tuberculosis.

Materials and Methods:

A total of 42 cases of newly diagnosed patients of cutaneous tuberculosis attending dermatology out patient department over a period of 1 year were included in the study. A detailed clinical examination and investigations including histopathological examination were carried out.

Results:

Scrofuloderma was the most common form seen in 50% cases followed by lupus vulgaris in 42.86%, tuberculosis verrucosa cutis in 4.76%, and lichen scrofulosorum in 2.38% cases. The Mantoux test was positive in 83.33% cases. Characteristic tuberculoid granulomas were seen in 72.22% cases of lupus vulgaris, 42.86% cases of scrofuloderma and all cases of tuberculosis verrucosa cutis and lichen scrofulosorum.

Conclusion:

Cutaneous tuberculosis is still highly prevalent in upper Assam. Early diagnosis and treatment are essential to prevent its complications.     

CONCOMITANT CUTANEOUS METASTATIC TUBERCULOUS ABSCESSES AND MULTIFOCAL SKELETAL TUBERCULOSIS

Tuberculosis, one of the oldest diseases known to affect humans is caused by the bacteria mycobacterium tuberculosis. The disease usually affects the lungs, although, in up to one third of cases, other organs are involved. Metastatic tuberculosis abscess is a rare form of skin tuberculosis. It is characterized by nodule and abscess formation throughout the body after hematogenous spread of mycobacterium tuberculosis from a primary focus during a period of impaired immunity. Tuberculosis osteomyelitis is also a rare form of extrapulmonary tuberculosis in pediatric age group. Skeletal tuberculosis pathogenesis is related to reactivation of hematogenous foci or spread from adjacent paravertebral lymph nodes. Weight-bearing joints are affected most commonly. Bilateral hand and foot bone involvement is rarely reported. We present a five-year-old girl with two very rare presentations of the disease such as osteomyelitis and metastatic skin abscess.     

INCREASED INCIDENCE OF TUBERCULOSIS IN PATIENTS OF SYSTEMIC SCLEROSIS ON DEXAMETHASONE PULSE THERAPY: A SHORT COMMUNICATION FROM KASHMIR

Background:

Systemic sclerosis is a multi-systemic autoimmune disorder affecting predominantly the skin, lungs, gut and kidneys.

Purpose:

To report the increased incidence of tuberculosis in patients of systemic sclerosis on dexamethasone pulse (DP) therapy.

Methods:

Forty-seven patients of systemic sclerosis were included in the study. After taking a complete history and doing a detailed physical examination, the patients were submitted to a battery of investigations including complete hemogram (CBC) with erythrocyte sedimentation rate (ESR(F)), Chest X-ray CXR (PA view) Mantoux test and urine analysis. CBC, ESR and urine examination was done monthly and CXR were repeated six-monthly.

Findings:

Seven patients on DP therapy developed genitourinary tuberculosis. Four had pulmonary tuberculosis. One patient developed tubercular lymphadenitis, one patient succumbed to miliary tuberculosis.

Conclusion:

There is an increased incidence of tuberculosis amongst patients of systemic sclerosis on DP therapy.

Limitation of the Study:

There was no control group of systemic sclerosis patients not on DP therapy to rule out the confounding effect of the disease per se predisposing to tuberculosis as all our patients as a matter of routine were put on steroid pulse. Also, the increased incidence of tuberculosis was detected incidentally while on monthly follow-up.     

Nodulo-ulcerative Tuberculosis of the Glans Penis—A Case Report and a Discussion on Nomenclature of Genital Tuberculosis

Lupus vulgaris is a chronic paucibacillary form of cutaneous tuberculosis occurring in a person with a moderate to high degree of immunity. It commonly occurs over the buttocks and trunk in India. Involvement of the genitalia is uncommon, and lesions involving the penis, extremely rare with few cases reported worldwide. There also exists a confusion regarding nosology of tuberculosis of the genitalia. A brief discussion and review of literature are being discussed along with the report of a case of genital tuberculosis involving the glans penis.     

Multifocal Annular Tufted Angioma: An Uncommon Clinical Entity

Tufted angioma (TA) is a localized benign hamartomatous vascular proliferation usually presenting in the childhood as an erythematous plaque. We report here a rare case of multifocal TA in an 8-year-old boy who presented which two large annular lesions as well as multiple papules and nodules on the back for the duration of 4 years. Histology showed typical well circumscribed poorly canalized vascular lobules with ‘cannon ball’ configuration.     

Acquired multifocal tufted angiomas in an immunocompetent young adult

Tufted angioma (TA) is a rare benign vascular neoplasm, localized to the skin and subcutaneous tissues, occurring primarily on the trunk and extremities of children. The lesions are usually asymptomatic but, rarely, paroxysmal painful episodes may be associated. The occurrence of eruptive TA is still rarer and had been described almost exclusively in association with immunocompromised states. We report here a case of acquired painful multifocal tufted angiomas on the face and neck in an immunocompetent young adult.     

A clinicoepidemiological study of 50 cases of cutaneous tuberculosis in a tertiary care teaching hospital in pokhara, Nepal

Background:

Cutaneous tuberculosis (TB) is essentially an invasion of the skin by Mycobacterium tuberculosis, the same bacteria that causes pulmonary tuberculosis.

Aim:

This study was conducted to study the common types of cutaneous TB and to find the management pattern in a tertiary teaching hospital in Pokhara, Nepal.

Materials and Methods:

All the cases of cutaneous TB were biopsied and furthermore investigated by performing Mantoux test, sputum examination, fine needle aspiration cytology, chest X-ray and ELISA.

Results:

In this study, we found that tuberculosis verrucous cutis (48%) had a higher incidence than other types of cutaneous TB. More males were affected than were females (1.2:1). Commonly affected sites were the limb and the buttock (48%). The most commonly affected age group was 16–25 years (40%). All cases (except two) were more than 15 mm in size in the Mantoux test. The histopathological picture was typical in all except three cases. All patients were treated with antitubercular treatment as per the national guidelines.

Conclusion:

The most common type of cutaneous TB was tuberculosis verrucous cutis and the most commonly affected sites were the limb and the buttock. As cutaneous TB sometimes reflects the presence of pulmonary tuberculosis, its incidence should not be ignored.     

Tuberculosis Verrucosa Cutis Presenting as Diffuse Plantar Keratoderma: An Unusual Sight

Tuberculosis verrucosa cutis (TVC) is a common cutaneous form of paucibacillary tuberculosis in an individual with moderate to high degree of immunity to Mycobacterium tuberculosis infection. Clinical appearance of TVC is mostly very typical with well-defined warty plaques presenting mostly on hands, knees, ankle, and buttocks; however several atypical morphology of the lesions have also been described. We hereby report a case of TVC, masquerading as asymptomatic diffuse keratoderma of left foot for nine months, in an otherwise healthy individual, obstructing easy diagnosis of cutaneous tuberculosis. Diagnosis was confirmed by histopathology.     

LICHEN SCROFULOSORUM: AN IMPORTANT MARKER OF OCCULT TUBERCULOSIS

Lichen scrofulosorum is a tuberculid that is usually seen in children or young adults. Although a rare occurrence, this tuberculid is an important marker of occult tuberculosis, which may not be detected otherwise. We report here a case of lichen scrofulosorum in a ten year-old boy with typical grouped lichenoid papules on the trunk associated with axillary tuberculous lymphadenitis.     

Poor neurological sequelae of herpes simplex virus encephalitis in an infant despite adequate antiviral and adjunct corticosteroid therapy

A 2-month-old infant presented to our emergency department with fever, altered consciousness, and focal seizures of acute onset. He had vesicular skin lesions over the right preauricular region. CT brain showed a large hypodense lesion involving the left temporo-parietal region, left basal ganglia and left thalamus. MRI brain revealed bilateral multifocal corticomedullary lesions suggestive of encephalitis. CSF-PCR was positive for herpes simplex virus (HSV) type I. He was treated with standard dose intravenous acyclovir for 15 days along with a trial of pulse methylprednisolone, but was readmitted within a week with features of an early relapse. The infant survived but developed significant neurological sequelae. Although treatment of HSV is available, the neurological outcome is guarded even with adequate antiviral therapy. Adjunct corticosteroid therapy did not appear to attenuate the neurological sequelae.     

HYPERTROPHIC LUPUS VULGARIS: AN UNUSUAL PRESENTATION

Lupus vulgaris is the most common form of cutaneous tuberculosis occurring in previously sensitized individuals with a high degree of tuberculin sensitivity. Various forms including plaque, ulcerative, hypertrophic, vegetative, papular, and nodular forms have been described. A 30-year-old male patient presented with a very large hypertrophic lupus vulgaris lesion over left side of chest since 22 years. Histopathological examination showed granulomatous infiltration without caseation necrosis. The Mantoux reaction was strongly positive. Hypertrophic lupus vulgaris of such a giant size and that too at an unusual site is extremely rare and hence is being reported.     

Skin as a marker of internal disease: a case of sarcoidosis

A 52-year-old female presented to our out patient department with asymptomatic, hypopigmented lesions on the neck and back since 2 months. There was a history of taking antitubercular treatment for suspected pulmonary tuberculosis 2 years back. On blood investigations, the serum angiotensin converting enzyme levels were increased and the skin biopsy revealed a naked granuloma in the dermis. A diagnosis of systemic sarcoidosis was made and the patient was started on oral corticosteroids and Methotrexate, with clinical improvement.     

Pyrazinamide-induced maculopapular rash

Pyrazinamide is a commonly used first-line antitubercular drug. Gastric-related adverse drug reactions are common with pyrazinamide. Dermatological manifestations due to pyrazinamide are rare. This study aimed find out the dermatological manifestations/adverse drug reaction (ADR) due to pyrazinamide. We reported a case of maculopapular rash caused by pyrazinamide in a patient on antituberculosis treatment using structured questionnaires. The patient developed maculopapular rashes on receiving combination antituberculosis treatment. The rashes disappeared after stopping the suspected drug. The patient was rechallenged with pyrazinamide, which led to reappearance of a similar type of rash. The causality, preventability, and severity were assessed using the Naranjo algorithm and Hartwig scale. Since pyrazinamide is a commonly used drug in tuberculosis and which is a common infectious disease in developing countries, with the similar reports, we can predict early case detection and can prevent the occurrence of similar reactions in future.     

Cutaneous manifestations of deep mycosis: an experience in a tropical pathology laboratory

Background:

Cutaneous manifestations of deep mycotic infection are fraught with delayed or misdiagnosis from mainly cutaneous neoplastic lesions.

Aim:

This study is designed to present our experience of these mycoses in a pathology laboratory in the tropics.

Materials and Methods:

A clinicopathologic analysis of deep mycotic infections was conducted over a 15 years period Formalin fixed and paraffin wax processed biopsies were stained with hematoxylin and eosin, periodic acid Schiff (PAS), and Grocott''s methenamine silver (GMS) for the identification of fungus specie. Patients’ bio-data and clinical information were obtained from records.

Results:

Twenty males and seven females presented with 6 months to 6 years histories of varying symptoms of slow growing facial swellings, nodules, subcutaneous frontal skull swelling, proptosis, nasal blockage, epistaxis, discharging leg sinuses, flank mass, convulsion and pain. Of the 27 patients, four gave antecedent history of trauma, two had recurrent lesions which necessitated maxilectomy, two presented with convulsion without motor dysfunction while one had associated erosion of the small bones of the foot. None of the patients had debilitating illnesses such as diabetes mellitus, tuberculosis, and HIV infection. Tissue histology revealed histoplasmosis (10), mycetoma (9), subcutaneous phycomycosis (6), and phaeohyphomycosis (2).

Conclusion:

Deep mycoses may present primarily as cutaneous lesions in immunocompetent persons and often elicit distinct histologic inflammatory response characterized by granuloma formation. Diagnosis in resource constraint setting can be achieved with tissue stained with PAS and GMS which identifies implicated fungus. Clinical recognition and adequate knowledge of the pathology of these mycoses may reduce attendant patient morbidity.     

DEXAMETHASONE PULSE THERAPY IN PATIENTS OF SYSTEMIC SCLEROSIS: IS IT A VIABLE PROPOSITION? A STUDY FROM KASHMIR

Background:

Systemic sclerosis is a multisystemic autoimmune disorder. Intravenous dexamethasone pulse therapy has been used since 1998.

Aim:

The aim wasto report the beneficial effects of dexamethasone pulse in patients of systemic sclerosis vis-à-vis the side effects.

Materials and Methods:

Forty-seven patients of systemic sclerosis were included. After looking at the history and physical examination, the patients were submitted to various relevant investigations. Clinical scoring of the patient was done at baseline and 6-month interval according to Furst''s organ indices score.

Results:

A total of47 patients of systemic sclerosis were included (45 females, 2 males). In majority, acrosclerosis was seen. Severe sclerosis and contractures were seen in two patients. Moderate proteinuria, restrictive lung disease, dysphagia, and valvular heart involvement were seen.A total of13 patients on dexamethasone pulse therapy developed tuberculosis. Improvement in skin scoring and decreased severity of Raynaud''s phenomenon was seen. No improvement in dysphagia, severe vascular symptoms, or restrictive lung disease was seen.

Conclusion:

Thus, beneficial effects of dexamethasone pulse therapy seem to be merely cosmetic.     

DETECTION OF R576 INTERLEUKIN-4 RECEPTOR AN ALLELE GENE, SERUM INTERLEUKIN-4, AND EOSINOPHILIC CATIONIC PROTEIN IN ATOPIC DERMATITIS PATIENTS

Atopic dermatitis (AD) is a chronic pruritic skin disease. It results from a complex interplay between strong genetic and environmental factors. The aim of this work was to study some biochemical markers of the dermatosis. This included detection of R576 interleukin-4 receptor alpha allele gene. Twenty five patients with AD and 25 controls participated in this study.     

Epidermolysis bullosa acquisita with moderately severe Dysphagia due to esophageal strictures

Epidermolysis bullosa acquisita (EBA) is a chronic, autoimmune condition involving the skin and mucous membranes. Symptomatic mucosal involvement is rare, but can impact on quality of life, due to esophageal strictures and dysphagia. We report a case involving a 60-year-old male presenting with bullous skin lesions on areas of friction on his hands, feet and mouth. Milia were visible on some healed areas. Biopsy showed a subepidermal vesicle. Direct immunofluorescence showed intense linear junctional IgG and C3 at the dermo-epidermal junction. Serological tests also supported the diagnosis of EBA. Screening tests for underlying malignancies were negative. Despite treatment with systemic steroids, the patient developed increasing dysphagia, requiring further investigation with esophagoscopy and a barium swallow. Confirmation of extensive esophageal stricturing prompted adjustment of medications including an increase in systemic steroids and addition of azathioprine. Currently, the patient's disease remains under control, with improvement in all his symptoms and return of anti-basement membrane antibody levels to normal, whilst he remains on azathioprine 150 mg daily and prednisolone 5 mg daily. This case highlights the fact that the treatment of a given patient with EBA depends on severity of disease and co-morbid symptoms. Newer immunoglobulin and biological therapies have shown promise in treatment resistant disease. Considering that long-term immunosuppressants or biologicals will be required, potential side effects of the drugs should be considered. If further deterioration occurs in this patient, cyclosporin A or intravenous immunoglobulin (IV Ig) will be considered. Vigilance for associated co-morbidities, especially malignancies, should always be maintained.
