11/51. Neutrophilic eccrine hidradenitis in a patient with Behcet's disease. patients with Behcet's disease may develop multiple mucocutaneous manifestations, several of which are mediated by neutrophils. These include aphthous ulcers, pseudofolliculitis, acneform lesions, and pathergy. We report another neutrophil-mediated disorder, neutrophilic eccrine hidradenitis (NEH), in a patient with Behcet's disease. NEH should be added to the list of mucocutaneous lesions that may be seen in patients with Behcet's disease. ( info) |
12/51. Neutrophilic eccrine hidradenitis in actinic reticuloid syndrome. Neutrophilic eccrine hidradenitis (NEH) is a rare, transient complication, which usually occurs in patients with leukemia receiving various chemotherapeutic regimens. However, similar eruptions have been observed in other conditions, including hiv-positive patients, and are often preceded by the onset of malignancies. We report the first case of NEH arising in a patient with actinic reticuloid syndrome who had been treated with methotrexate. ( info) |
13/51. Neutrophilic eccrine hidradenitis secondary to topotecan. BACKGROUND: Neutrophilic eccrine hidradenitis (NEH) is a self-restricted inflammatory condition, usually secondary to chemotherapeutic agents and less frequently to other drugs such as zidovudine or various infections. NEH clinical features include erythematous, occasionally painful nodules and plaques. Histological examinations reveal neutrophilic infiltrates and degeneration of eccrine glands. methods: A 45-year-old female was treated with topotecan and colony-stimulating factor for ovarian cancer. RESULTS: The erythematous and slightly pruritic plaques on the upper and lower limbs and ear lobes appeared approximately 1 week after chemotherapy and spontaneously subsided in about 10 days, only to recur after the next drug dose. A skin biopsy revealed NEH; all skin cultures were negative. CONCLUSION: It is believed that this patient developed topotecan-induced NEH; this relationship with therapy rather than the underlying disease rules out a paraneoplastic reaction, and negative cultures excluded infectious causes. In addition, since skin lesions recurred after CSF was discontinued, this agent was not involved. Studies relating NEH to topotecan, a topoisomerasa I inhibitor, have not reported such an event in the literature. ( info) |
14/51. Chronic pruritic neutrophilic eccrine hidradenitis in a patient with Behcet's disease. Neutrophilic eccrine hidradenitis (NEH) is a rare distinct entity that usually presents as asymptomatic erythematous papules that disappear spontaneously in 1-3 weeks. However, its appearance may be polymorphic, pruritic, recurrent or even chronic as is described in this case. The histological combination of neutrophilic infiltration in and necrosis of the eccrine secretory gland epithelium is highly characteristic for NEH. It typically occurs in patients receiving chemotherapeutic drugs for malignancies, but other associations have also been reported. To our knowledge, we report the first case of NEH in a patient with Behcet's disease (BD). Cutaneous manifestations of BD, an inflammatory systemic disorder of unknown origin, include neutrophilic dermatoses such as Sweet's syndrome and pyoderma gangrenosum, although these are unusual in BD. NEH could be another neutrophilic dermatosis related to BD. This observation suggests that NEH is not strictly related to chemotherapeutic drugs and malignancies. It appears to be a reactive dermatosis associated with other factors as well, including BD. Treatment was successful with dapsone 100 mg daily. ( info) |
15/51. Pustular idiopathic recurrent palmoplantar hidradenitis: an unusual clinical feature. A 12-year-old boy had painful lesions on both soles. He had had a similar episode several months before that resolved spontaneously. physical examination showed erythematous, extremely tender nodules on both plantar surfaces and the toes. The second and third left toes had small pustules on top of the nodules. There was no palmar involvement. The clinical features, pathologic findings, and self-limited course suggested recurrent palmoplantar hidradenitis. This distinctive entity of unknown origin appears during childhood and is characterized histologically by a neutrophilic infiltrate affecting the eccrine glands. We report the case of a patient with unusual clinical features. ( info) |
16/51. Neutrophilic eccrine hidradenitis heralding the onset of chronic myelogenous leukaemia. Neutrophilic eccrine hidradenitis was initially described in acute myelogenous leukaemic patients undergoing chemotherapy, suggesting a drug-induced mechanism. It has been reported in some with various neoplastic and non-neoplastic conditions as well as in healthy individuals. However, most the reported cases have been described in acute myelogenous leukaemic cases receiving chemotherapy. We describe a neutrophilic eccrine hidradenitis case unassociated with chemotherapy in a woman with chronic myelogenous leukaemia. ( info) |
17/51. Neutrophilic eccrine hidradenitis mimicking cutaneous vasculitis in a lupus patient: a complication of cyclophosphamide. Neutrophilic eccrine hidradenitis (NEH) is an unusual self-limited skin disorder characterized by an inflammatory cell infiltrate in the deep dermis involving the eccrine sweat glands, commonly presenting as painful cutaneous nodules. NEH occurs most frequently in patients receiving chemotherapy for haematologic malignancies. We report a case of NEH masquerading as cutaneous vasculitis in a woman receiving cyclophosphamide for lupus nephritis. The association of NEH and the use of cytotoxic agents for SLE or other autoimmune diseases has not been reported previously. NEH must be considered in lupus patients receiving cytotoxic agents to avoid inappropriate use of corticosteroids or antibiotics in this self-limited condition. ( info) |
18/51. Recurrent neutrophilic eccrine hidradenitis. Neutrophilic eccrine hidradenitis (NEH) is a neutrophilic dermatosis primarily affecting the eccrine glands, and most commonly seen in patients undergoing chemotherapy for treatment of a malignancy. Rapid diagnosis may avert unnecessary changes in therapy to treat conditions which clinically mimic NEH. We describe a patient who developed NEH on three separate occasions provoked by two different chemotherapeutic agents--cytarabine and mitoxantrone. The lesions were morphologically distinct and differed in their anatomical distribution during each episode. The response to intravenous corticosteroids was dramatic, but lesions recurred after their withdrawal. This case illustrates the potential diversity of clinical lesions in a single patient with NEH, and its response to systemically administered corticosteroids. ( info) |
19/51. Recurrent palmoplantar hidradenitis with exclusive palmar involvement and an association with trauma and exposure to aluminum dust. Recurrent palmoplantar hidradenitis is a benign, self-limited inflammatory skin condition that has been reported to occur on the soles and palms of otherwise healthy children and young adults. patients with the disease present with tender, erythematous and edematous plaques and nodules on the palmoplantar skin. We describe a child who had recurrent palmoplantar hidradenitis that occurred after trauma and exposure to aluminum dust and manifested as lesions localized to only the palmar surfaces. This case is presented to add exclusive palmar involvement to the diagnostic spectrum of recurrent palmoplantar hidradenitis and to review the proposed pathogenesis of the disease. ( info) |
| We report on a patient with hidradenitis suppurativa with premenstrual exacerbations, who was treated successfully with total abdominal hysterectomy and bilateral salpingo-oophorectomy combined with estrogen substitution. As a trial, she was initially treated successfully with a gonadotropin-releasing hormone agonist and subsequently a gonadotropin-releasing hormone agonist in combination with estrogen substitution.
