Protothecosis is a rare cause of systemic and/or cutaneous infection. Because approximately 100 cases of human infection with Prototheca wickerhamii have been reported, little is known about the pathogenesis of this infection. Cases include both immunocompetent and immunocompromised patients. However, most cases contain an element of immune compromise, either local or systemic. We present a case of an 81-year-old white woman with a history of multiple nonmelanoma skin cancers, including squamous and basal cell carcinomas and actinic keratoses, throughout her legs and thighs bilaterally. She presented to a central Florida dermatology clinic with complaints of persistent bumps on her right lower leg despite therapy with diclofenac sodium gel 3% and 5-fluorouracil cream 5%. Biopsies of skin specimens from the right lower leg revealed a dermal abscess that contained spherical funguslike organisms, with periodic acid-Schiff staining revealing 6- to 10-microm organisms with internal septations, which are characteristic of P wickerhamii. 相似文献

A patient is reported who had ataxia telangiectasia with multiple cutaneous lesions mainly on the limbs, which showed atrophy and scarring. Histopathology of these skin lesions showed tuberculoid granulomas without frank collagen necrobiosis in the dermis. Chromosomal analysis revealed a translocation between 7 and 14 as well as deletion of chromosomes 4 and 6. 相似文献

Cutaneous lymphadenoma: a case report and review of the literature 总被引:10,自引:0,他引:10
We report a case of cutaneous lymphadenoma, a tumour first described by Santa Cruz and Barr under the name of‘lymphoepithelial tumour1. Twenty-three cases have been reported to date. The commonest site is the head and neck, and it is most commonly diagnosed in the fourth and fifth decades. The usual clinical diagnosis is basal ceil carcinoma. To date, no recurrences have been observed after iocai excision. The tumour is C(miposed of dermal lobules with a biphasic pattern of epithelial and lymphoid cells. It has been suggested that it arises as a result of faulty interaction between lymphocytes and epithelial cells. 相似文献

Cutaneous granulomatous vasculitis associated with lymphoproliferative disorders is a rare entity, with only 14 cases previously reported in the English literature. Patients generally present with nodules or ulcers involving the extremities, which can appear months or years before or after onset of systemic disease. Granulomatous vasculitis has a poor prognosis when associated with underlying lymphoproliferative disorders, with the majority of reported cases fatal. Knowledge of this unusual entity is important to allow for proper clinical evaluation, follow-up, and therapy. We report a 77-year-old female with chronic lymphocytic leukemia and granulomatous vasculitis, which highlights the features of this association, and expands the clinical data. 相似文献

Cutaneous disease is a previously reported but unusual presentation for schistosomiasis. We report a case of Schistosoma haematobium infection that appeared 3 years after exposure, with skin lesions as the sole manifestation. The diagnosis was made on the basis of a routine skin biopsy and the patient did well after therapy with praziquantel. Dermatologists should be aware of this presentation of schistosomiasis when evaluating patients with unusual skin lesions who have traveled in areas where schistosomiasis is endemic. 相似文献

Background Cutaneous pili migrans is a rare condition in which the hair shaft penetrates the superficial layer of the skin and produces a creeping eruption mimicking the lesion of cutaneous larva migrans.
Methods We report a 28-year-old Chinese man who presented with a painful and slow-moving black, linear eruption on the left sole after walking on a waterlogged street wearing slippers without socks.
Results The lesion started at the anterior part of the foot near the external border, extending linearly along Langer's line towards the lateral side. It then turned in a U-shaped direction and moved across the foot to the other side, where it made a right angle and moved along the internal side of the foot. The lesion was reminiscent of cutaneous larva migrans. Walking made the line move more quickly. Physical examination showed that there was a broken epidermis at the probable entrance and a black thin line at the advancing end of the lesion. The black line was demonstrated to be a hair shaft with a sharp head by a shallow incision of the skin and examination under a microscope. After removal of the hair, the pain disappeared and the lesion diminished immediately, leaving slight pigmentation.
Conclusion The broken epidermis may be one of the main reasons for the hair shaft entering the skin. The force of body motion caused movement, which was made easier by the sharp head of the hair shaft. Hair can produce an eruption reminiscent of cutaneous larva migrans. 相似文献

Aplasia cutis congenita (ACC) is a relatively rare congenital anomaly that most commonly occurs as a solitary cutaneous defect on the scalp. Depth of involvement varies, and involvement of deeper calvarium and dural structures can be seen in more severe cases. Multiple classification systems have been devised with the Frieden Classification System being the most widely adopted. Using this system, we describe a patient that developed Type V ACC with associated fetal papyraceous. The child healed remarkably well with the application of petrolatum impregnated gauze and topical silver sulfadiazine twice daily for approximately 4 weeks. The child was noted to have no significant contractures or complications at 6‐months and 1‐year follow‐up exams. Herein, we review the current literature on type V ACC including a discussion of treatment options. 相似文献

Aplasia cutis congenita is a rare condition characterized by the absence of skin and sometimes other underlying structures such as bone or dura. It can be a part of various syndromes and can be associated with multiple genetic diseases, malformation patterns, or a combination of all. It is even considered as a form frustre of a neural tube defect in several literatures. Bullous aplasia cutis congenita is a clinical subtype of the condition, with extremely few cases reported in the literature. It presents as a cystic or bullous lesion at birth, which eventually transforms into an atrophic, flat scar covered by a thin epithelium. Some cases present with a dark collar hair sign around the lesion, which can be even more indicative of an underlying neural tube defect. Management remains controversial and depends on the characteristics of the lesion, but conservative treatment is usually chosen. 相似文献

Kaposi's sarcoma (KS) of childhood is an extremely rare and unexplained disease. It is usually associated with immunosuppression and human herpes virus 8 (HHV-8) infection. It can involve skin, mucous membranes, lymph nodes and viscera. This investigation describes a case of a 3-year-old boy with cutaneous and lymphangiopathic KS. Initially, the patient presented with cutaneous lesions of KS behind the right ear. Two months later, the disease disseminated not only cutaneously but also to the cervical, axillary and inguinal lymph nodes. Immunological evaluation showed severe lymphocytopenia but without evidence of human immunodeficiency virus infection. The vascular nature of the lesion was supported by positive staining for CD31 and CD34. This study examines the clinicopathologic features of KS in children and summarizes the relevant literature. 相似文献

Carcinosarcomas are malignant neoplasms with biphasic carcinomatous and sarcomatous or sarcoma‐like components. In general, the sarcomatous component is accepted to be the result of divergent mesenchymal differentiation of the epithelial component. Although well characterized in some anatomic locations (e.g. uterus, upper aerodigestive tract and lung), carcinosarcomas of the skin are rare. Reported epithelial components include squamous, adnexal, neuroendocrine and basaloid. Including this case, only 47 cases of primary cutaneous basal cell carcinosarcoma have been reported in the literature to date. We performed an extensive immunophenotypic evaluation in our case, which confirmed the previously reported coexpression of p53 in both components, and revealed a hitherto unreported coexpression of p16 and p63. Additionally, this report reviews the clinical, pathologic, immunophenotypic characteristics and outcomes of the basal cell carcinosarcomas reported in the literature, in order to emphasize the overall uniform characteristics and clinical behavior of this neoplasm. 相似文献

We report the occurrence of a malignant melanoma in a patient with neurofibromatosis (von Recklinghausen's disease; NF 1). Neurofibromatosis, like malignant melanoma, is believed to be a disorder of neural crest origin, and is associated with a number of different malignancies, but a definite association between cutaneous malignant melanoma and neurofibromatosis has not been established. We describe a patient with a malignant melanoma and with neurofibromatosis, and review the literature pertinent to this topic. The malignant melanoma was not related to a café-aulait patch or congenital naevus. The paucity of reports of patients with neurofibromatosis associated with cutaneous malignant melanoma suggests that these diseases probably do not occur together with any greater frequency than that determined by chance alone. 相似文献

Cutaneous lymphoid hyperplasia (CLH) is considered a benign lymphoid reactive process that results from various antigenic stimuli and may have potential for progression to overt lymphoma. CLH lesions may closely resemble lymphoma both clinically and histologically. We present a case of a 54-year-old woman who spontaneously developed lesions of unknown cause consistent with CLH. We also review the literature and discuss the etiology, clinical features, diagnosis, and management of CLH. 相似文献
