Seborrheic keratoses (SKs) are common epidermal tumors composed of benign keratinocytes. Malignant skin tumors including basal cell carcinoma (BCC) rarely arise within SKs. We report a rare case of an 82-year-old man with nodulocystic BCC that appeared at the center of a scaly hyperpigmented SK that had been presented for more than 10 years. It was histologically confirmed that CK19-positive BCC arose directly from the wall of the pseudohorn cyst, a part of the SK. Nodular and/or cystic BCC also rarely arise within SKs while the most common histologic type of BCC within SKs is the superficial type. Careful observation of SKs is important even though it is rarely a background condition for malignant transformation.  相似文献

A 51-year-old male presented with blackish discoloration of nails of 10 months duration. Examination revealed black dystrophic left thumb finger nail. Detailed examination showed a mass under the dystrophic nail. Hutchinson sign was positive. Histopathology revealed characteristic features of melanoma. A detailed evaluation revealed no features of local or distant metastasis. The entire lesion was then removed surgically along with disarticulation at the interphalangeal joint. Resection-free margin was confirmed. This case is being reported for the rare occurrence of subungual melanoma in the Indian population and also for presentation with a long history of lesion with no evidence of metastasis.  相似文献

Chondroid syringoma (CS) is an uncommon benign adnexal tumor of the skin with eccrine and apocrine origin, which usually involves the head and neck region. The presentation of CS in other areas of the body is rare. A 45-year-old male patient presented to the dermatology clinic with a chief complaint of a painless, slow-growing mass on his left forearm, which gradually developed over the course of 2 years. A solitary, firm, purple, mobile, non-tender nodule was located in the distal part of left dorsal forearm, which was 1.8 cm in diameter. The tumor was surgically excised and sent for the histopathological evaluation. Results of biopsy and hematoxylin and eosin staining confirmed the diagnosis of CS and showed no evidence of malignancy. Although CS is an uncommon tumor in uppr limb region, it should be considered as one of the differential diagnoses, when dealing with tumors of this area.  相似文献

A 27-year-old healthy man presented with non-itchy hyperpigmented skin lesions involving the trunk of duration 3 years. Examination revealed numerous coalescing, rough, slightly elevated brownish papules involving large areas of back, chest, and abdomen. There were no other cutaneous or systemic findings. Cutaneous biopsy was suggestive of verruca plana, which confirmed our clinical diagnosis. Here, we report this case of verruca plana due to its rare extensive involvement and unusual site in a non-immunocompromised individual.  相似文献

Bowenoid papulosis is a rare condition of the genital area caused by human papilloma virus. Clinically, it resembles viral wart and histopathologically Bowen''s disease. We herein report two male patients presenting with multiple flat papules on the penis and scrotum. The second patient was HIV-positive. Histopathology showed features of bowenoid papulosis. Both the patients were treated with topical tazarotene gel 0.05%. Lesions cleared within 2 weeks in both the patients.Second patient had recurrences that cleared after retreatment with tazarotene.  相似文献

X-linked ichthyosis is a rare form of dermatological disease and when it presents as erythroderma it is even rarer. History of consanguineous marriage and prolonged labor during birth of patient, generalized scaling which gets better in summer months, flexural involvement, cryptorchidism made a diagnosis of X-linked ichthyosis. We report this case because of its rarity as erythroderma.  相似文献

A 50-year-old man presented with slow-growing dry, rough, micaceous scaly plaque over glans penis, which was compatible with clinical diagnosis of pseudoepitheliomatous keratotic and micaceous balanitis (PKMB) and histologically suggestive of PKMB without cellular atypia. He was treated successfully with topical 5-fluorouracil with complete clearance of lesion in 3 weeks without recurrence for 10 months. PKMB is an extremely rare and interesting condition; only a handful cases have been reported in world literature.  相似文献

A 25-year-old woman patient presented with shortening of fingers with racket nails and numerous yellowish papules over the hands and forearms for 21 years. X-ray of the hands revealed destructive osteolytic changes in all the terminal phalanges. Skin biopsy from the yellowish papules showed epidermal proliferation, perivascular mononuclear infiltrate, thickening of dermal collagen, septal fibrosis and loss of adipocytes mimicking sclerodermatous changes in the dermis and hypodermis. The patient did not have any history of similar illness in the family or occupational exposure to vinyl chloride. After excluding all other possibilities of acral-osteolysis, we diagnosed the case as idiopathic non-familial variety of acro-osteolysis. This is a rare entity characterized by terminal resorption of fingers, sometimes associated with Raynaud''s phenomena and yellowish cutaneous papules.  相似文献

Chlorhexidine is a widely used antiseptic and disinfectant in medical and non-medical environments. Compared to its ubiquitous use, allergic contact dermatitis from chlorhexidine has rarely been reported and so its sensitization rate seems to be low. Chlorhexidine has been used for more than 50 years but it was only in the last two decades, that reports of immediate- type reactions to chlorhexidine were seen. Reactions ranging from localized urticaria to anaphylactic shock and hypersensitivity reactions, including delayed hypersensitivity reactions such as contact dermatitis, fixed drug eruptions, and photosensitivity reactions, began to appear more frequently. However the prevalence of contact urticaria and anaphylaxis due to chlorhexidine remains to be unknown. In this case report we have reported a case of urticaria due to oral use of chlorhexidine. The adverse reaction was confirmed by a skin prick test.  相似文献

We are reporting a case of superficial spreading melanoma (SSM) on left palm of a 37-year-old pregnant housewife. She had a small acquired melanocytic nevus on her left palm since childhood, which changed its consistency and color in the last 4 months. Dermoscopy of the lesion indicated malignant changes. The lesion was managed surgically using split-thickness skin graft. The histopathology report was suggestive of SSM with positive HMB-45 cells. SSM is very rare on the acral site, and it is very difficult to differentiate it from acral lentiginous melanoma. The rarity of the site (acral nonchronic sun damage) with evolution during pregnancy and importance of management approach are reasons for publishing this case.  相似文献

Ichthyosis hystrix is a term used to describe an ichthyosiform dermatosis which is characterized by hyperkeratotic spiny scales mainly over extensor aspects of limbs with palmoplantar keratoderma and occasionally associated with deafness and neurological deficit. It is a rare autosomal dominant form of ichthyosis and very few cases are reported in literature. We are presenting a 46 years-old-male patient of ichthyosis hystrix with unusual presentation. He had lesions mainly over the face and scalp with palmoplantar keratoderma and significant nail changes.  相似文献

Mastocytosis is defined as a heterogeneous group of disorders characterized by an accumulation of mast cells in one or more organs, particularly in the skin, bone marrow, liver, spleen and lymph nodes. However here we describe an 11-month-old girl child presented with diffuse cutaneous mastocytosis with bullous lesion, having pulmonary involvement, which is very rare and there is no available case report from India.  相似文献

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare and idiopathic vascular disorder. It is characterized by red to brown papules and nodules, typically localized on the head and neck, particularly around the ear as singular or multiple lesions. Although ALHE is a benign disease, lesions are often persistent and difficult to eradicate. Young to middle age women are more commonly affected. The histological examination corresponds to a florid vascular proliferation with atypical endothelial cells surrounded by a lymphocytic and eosinophilic infiltrate. We describe an elderly male with multiple nodular lesions over the scalp mimicking cylindromas; the histological examination was consistent with ALHE.  相似文献

Amyloidosis is a group of heterogeneous diseases characterized by pathological deposition of proteinaceous substance extracellularly in various tissues. The clinical presentation depends on the site of amyloid deposition, with predominant involvement of mesenchymal elements and cutaneous findings in 30–40% of patients in case of primary systemic amyloidosis. We present a case of idiopathic primary systemic amyloidosis presenting with an unusual finding of nodulo-ulcerative lesion over tongue along with multiple skin-colored nodules, mimicking squamous cell carcinoma of tongue with secondary cutaneous metastasis, as well as lacking the classical presentation of purpura, macroglossia, waxy papules, and plaques.  相似文献

Carcinoma of the cervix is the second to fourth most common malignancy in women. It metastasizes most often to the lungs, bones, and liver. Skin involvement originating from cervical cancer is rare, even in the terminal stages of the disease. Cutaneous metastasis of cervical cancer usually presents as cutaneous nodules, papules/plaques, maculopapular rash, and diffuse inflammatory rash. We report a rare case (only the second reported case to the best of our knowledge) of a 50-year-old woman with cutaneous metastasis in form of fungating ulcerative growth on mons pubis as presenting feature of carcinoma cervix.  相似文献

Background:

Basal cell carcinoma (BCC) is the most common skin cancer among Caucasians, and in most cases, occurs in the sun-exposed areas. In recent years, in addition to many other etiologies such as exposure to UV radiation, and occasionally xeroderma pigmentosa, burns, tattoos, and pox scars, human papillomavirus (HPV) is also considered to have an etiologic role. Different studies were conducted with varied results in this regard.

Aims:

We evaluate this plausible relationship between HPV and BCC by means of immunohistochemistry (IHC) staining method.

Methods:

This is an analytic cross-sectional study in which 160 samples were selected randomly consisting of 80 BCC lesions and 80 safe margins. Sampling was done among paraffin-embedded blocks in pathology ward of Kashani and Alzahra hospitals, Isfahan-Iran, from 2004-2007. A section of each block was IHC stained for HPV immunoreactivity (DAKO, Denmark). This was followed by microscopic evaluation in terms of being positive or negative.

Results:

Fifty seven point five percent of the samples belonged to men and the others to women. In 10%, HPV marker was positive, both in lesion and margin. In 83.8% neither the lesions nor the margins were immunoreactive for HPV. Only in 5 cases (6.3%) the lesion was positive and the margin was negative for this marker. There was no case of immunoreactivity for HPV marker in margins, while it was negative in lesions. Our study results followed by McNemar analysis did not show a significant relationship between BCC incidence and HPV existence. This was consistent in both genders (P > 0.05, power > 90%).

Conclusion:

In this study we did not find a significant relationship between BCC and HPV, but based on review of articles it appears that large multicentric studies are to be conducted in this regard.  相似文献

Varicella zoster virus causes varicella which is a common disease. Generally it is self-limiting, and treatment is often unnecessary, but severe or life-threatening complications are rarely seen. We report a case of fulminant varicella complicating with purpura fulminans, hepatitis, and probable rhabdomyolysis in a previously healthy child.  相似文献

Background:

Treatment of plantar warts caused by human papilloma virus (HPV) strain types 1, 2 and 4 is often difficult and a challenging problem. Various therapeutic modalities available for treating this problem have not been uniformly successful.

Purpose:

The purpose of present study is to evaluate the efficacy of adapalene applied locally with occlusion in plantar warts.

Materials and Methods:

A total of 10 patient with 118 plantar warts were included in an open study. All were treated by applying adapalene gel 0.1% after paring of warts if needed followed by occlusive dressing with polythene paper in each patient. The effects of the treatment were evaluated every week till the clearance of all warts.

Findings:

Adapalene was used in 10 patient having 118 plantar warts. All the warts cleared in 39±15.07 days. There was no side effects like scar formation, irritation, erythema or infection with adapalene.

Conclusion:

Adapalene clears the plantar warts faster compared to other modalities available.

Limitation:

Need trial with large number of patients.  相似文献

Diffuse neurofibroma is an unusual variant of neurofibroma with the head and neck being the common sites of involvement. It is benign in nature and spreads superficially and has many ectatic blood vessels. Histologically it is similar to conventional neurofibromas except for a few peculiar distinguishing features. We report a case of a 14-year-old boy who presented with a diffuse recurrent painless swelling over the dorsum of the nose with the clinical stigmata of neurofibromatosis. Microscopy revealed a diagnosis of diffuse neurofibroma with a few foci showing differentiation towards Meissner''s type of tactile corpuscles. It is important to recognize this entity as it has a tendency to recur, yet hardly ever become malignant and is almost always associated with neurofibromatosis type 1.  相似文献

Background:

Warts are caused by various strains of Human Papilloma Virus. They involve the epithelium of the skin and mucus membrane. Various treatment options are available, but extensive and recalcitrant warts not only cause distress to the patient cosmetically and psychologically but also pose a therapeutic challenge to the treating dermatologist.

Aim:

To evaluate the efficacy of autowart injection as a treatment option for extensive and recalcitrant warts.

Materials and Methods:

Autowart injection was prepared by removing 3 to 4 mm size wart with radiocautery which was crushed under aseptic condition and injected in the gluteal region by suspending in water for injection.

Result:

Results were evaluated in 53 available patients who turned up for follow-up; 35 patients (66.03%) had complete resolution in 2 months time, 12 patients (22.64%) showed partial improvement, whereas six patients (11.32%) had no improvement.

Conclusion:

Autowart injection is suggested as an effective and noninvasive therapeutic option in extensive and recalcitrant warts where most of the available therapies are inconvenient for both patient and treating dermatologist.  相似文献
