1/4. steatocystoma multiplex suppurativum: oral isotretinoin treatment combined with cryotherapy.A 30-year-old man presented with numerous papules, nodules and inflamed cysts. The lesions were located all over the body, including the scalp, except the palms and soles. His mother and one sister had had similar but less extensive lesions. Histopathology of the biopsy specimens obtained from the anterior chest wall, axillae and the back region was consistent with steatocystoma multiplex (SM). A diagnosis of steatocystoma multiplex suppurativum was made. The inflamed lesions were treated with oral isotretinoin (1 mg/kg per daily) for 6 months. At the same time, cryotherapy was used for non-suppurating lesions smaller than 2 cm. When the patient was evaluated 6 months later, cosmetic results were good. No new lesions have appeared in the subsequent 12-month follow up.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
2/4. Aquagenic syringeal acrokeratoderma (transient reactive papulotranslucent acrokeratoderma).In 1996, English and McCollough described an unusual entity in 2 sisters characterized by a transient and recurrent keratoderma exclusively on the palms after water exposure. The condition developed 3-5 min after exposure to water and resolved within a short time after drying. This finding was associated with a tightening sensation. Yan et al. coined the term 'aquagenic palmoplantar keratoderma', and the designation 'aquagenic syringeal acrokeratoderma' was suggested by MacCormack et al. Until now, a total of 8 cases have been reported. We documented 2 new cases with acquired aquagenic syringeal acrokeratoderma. A 25-year-old female had observed within the last 3 months a burning sensation on the palms after some minutes of water contact. physical examination revealed a perfectly normal skin on the palms. Three minutes after water immersion of 20 degrees C, a whitish discoloration appeared on the palms and a thickening of the palmar skin was visible. In addition, the eccrine pores were much more prominent. Few minutes after drying the skin, the situation returned to a normal state. The second patient, a 33-year-old female noticed a painful whitish discoloration of the skin on the palms after a short period of water immersion. Sometimes the white skin could be peeled off. In the last year, hyperhidrosis developed, and a more reddish aspect of the palms appeared. In our office after rinsing the hands with water at room temperature, a whitish discoloration in the center of the palms appeared which was associated with a painful sensation. After drying, the whitish lesions disappeared almost completely within 30 min. Aquagenic palmar keratoderma describes an acquired and transient condition which occurs after brief exposure to water and disappears after drying within minutes to an hour. Only rarely may a slight hyperkeratosis remain for a longer time. The possible pathophysiology and treatment options are discussed.- - - - - - - - - - ranking = 10keywords = palm (Clic here for more details about this article) |
3/4. A case of AIDS manifesting pruritic papular eruptions and psoriasiform lesions: an immunohistochemical study of the lesional dermal infiltrates.A 63-year-old man was referred to our department on September 14, 1992, because of multiple red papules with severe itching. Pruritic papular eruption (PPE) in a human immunodeficiency virus (hiv)-infected patient was diagnosed based on the histological findings, the reduction in CD4, and positive results for hiv antibody. In September of 1993, papules and erythematous plaques with scales appeared on both the palms and soles. The erythema was pruritic and spread gradually to the extremities and trunk. These plaques with erythema and scales are similar to those of the psoriatic lesions seen in Reiter's syndrome, although the HLA typing was not B27. Immunohistopathological findings of the papules of PPE and plaques of psoriasiform lesions showed that perivascularly infiltrated cells in the dermis were mostly lymphocytes. The lymphocytes in PPE were positive for CD45 and negative for CD3, CD43, and CD45RO, but the lymphocytes in psoriasiform lesions were positive for CD45, CD3, and CD43. Moreover, 20-30% of these lymphocytes were also intensely positive for CD45RO. These observations were similar to those obtained in the lesional skin of hiv-negative psoriasis, suggesting that there were no significant immunohistopathological differences in the abnormality of local cellular immunity related to the formation of psoriasiform lesions in hiv-negative psoriasis and hiv-positive psoriasis.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
4/4. Acquired relapsing self-healing Blaschko dermatitis.We describe a 44-year-old woman who had a unilateral relapsing linear dermatosis for 12 years. The lesions consisted of erythematous, discrete and grouped papules and papulovesicles that were localized to the left side of the upper and lower limbs, chest, abdomen, and back. They were distributed along Blaschko's lines. There was also a diffuse erythematous scaly hyperkeratosis of both palms. The lesions healed spontaneously. Examination of biopsy specimens from the back and the left palm revealed acute and subacute spongiotic dermatitis, respectively. This dermatosis was first described by Grosshans and Marot in 1990 and termed "Blaschkite de l'adulte." Because the disease is acquired, relapsing, heals spontaneously, follows Blaschko's lines, and is characterized histopathologically by a spongiotic dermatitis, we propose the term "acquired relapsing self-healing Blaschko dermatitis."- - - - - - - - - - ranking = 2keywords = palm (Clic here for more details about this article) |
