1/65. Acral keratotic graft versus host disease simulating warts.A 55-year-old man experienced persistent oral graft versus host disease after receiving an HLA-matched allogeneic stem cell peripheral blood transplant for chronic myeloid leukaemia. Twelve months post-transplant, multiple keratotic lesions resembling warts developed on his fingers, on his palms and on the soles of his feet. skin biopsy showed a lichenoid reaction under a hyperplastic and hyperkeratotic epidermis lacking signs of papillomavirus infection. The lesions partially regressed when the patient's oral prednisone was increased. This instance of acral keratotic lesions may represent an unusual expression of chronic graft versus host disease; however, the the hydroxychloroquine which had been used for 8 months to control the patient's oral graft versus host disease cannot be excluded as a cofactor.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
2/65. Keratotsis punctata of the palmar creases: report of two cases associated with ichthyosis vulgaris.Two patients with keratosis punctata of the palmar creases are described. The association with ichthyosis vulgaris and other disorders of keratinization is discussed. In both cases, histopathology revealed a close relation between the keratotic plug and the sweat glands. The role of genetic factors and manual activity in the pathogenesis is discussed. Treatment with oral etretinate resulted in a good improvement in the first patient, but prolonged low-dose maintenance therapy was required to prevent recurrence.- - - - - - - - - - ranking = 5keywords = palm (Clic here for more details about this article) |
3/65. Receptor tyrosine kinase and p16/CDKN2 expression in a case of tripe palms associated with non-small-cell lung cancer.BACKGROUND: Tripe palms is a descriptive term for a cutaneous paraneoplastic keratoderma. Tripe palms are frequently associated with gastric and pulmonary carcinoma. The pathogenetic mechanism remains unknown. OBJECTIVE: To determine the influence of receptor tyrosine kinases, which are both expressed in pulmonary carcinomas and in human skin, we performed expression studies on epidermal growth factor receptor (EGFR), HER2, HER3 in a skin sample of tripe palms obtained from a patient with non-small-cell lung cancer with lymph node involvement. Two months after diagnosis, the patient had developed palmoplantar 'tripe palms'. Additionally, the expression of SRC, c-myc and p16/ CDKN2 were studied. METHOD: Conventional reverse-transcription polymerase chain reaction was performed on a tissue sample of tripe palms. RESULTS: Weak expression of HER2 and of p16/CDKN2 was found. EGFR, HER3, c-myc and SRC were not expressed. CONCLUSION: Receptor tyrosine kinases of subclass I, the tyrosine kinase SRC and the oncogene c-myc play no major role in the pathogenesis of this case of tripe palms. copyright (R) 2000 S.

4/65. Acrokeratosis paraneoplastica (Bazex syndrome) with adenocarcinoma of the colon: report of a case and review of the literature.Acrokeratosis paraneoplastica is a rare disease and is uncommon even in patients with upper aerodigestive tract cancer. We report a 63-year-old man with a 1-month history of numerous pruritic lesions and vesicles on both feet. Although he had received local therapy, progressive dense scale formation involving both palms and both soles was found. colonoscopy was performed because of hematochezia, and it revealed an early colon cancer. After the resection of the cancer, the skin lesions began to fall off dramatically. To the best of our knowledge, there is no report of acrokeratosis paraneoplastica associated with colon cancer in the literature. This is the first case report of acrokeratosis paraneoplastica associated with early colon cancer.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
5/65. Spiny keratoderma.Spiny keratoderma is a descriptive term used to encompass a variety of unusual, disparate keratodermas. Spiny keratoderma has been associated with lipid abnormalities and has been limited to the palms and soles in some individuals. We describe an acquired case of spiny keratoderma in which an adult woman developed filiform lesions predominating on the trunk and proximal extremities. Treatment with topical emollients and keratolytic agents was unsuccessful, but topical tazarotene led to long periods of resolution. She has had no other associated abnormalities. The clinical features and differential diagnosis of spiny keratoderma are reviewed.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
6/65. Spiny keratoderma of the palms and soles - report of two cases.We report two patients with spiny keratoderma of the palms and soles characterized by multiple tiny keratotic plugs on the palms and soles. This disease was reported to be possibly associated with internal malignancies. We found a tumor from the esophagus to cardia in one patient. Another had no tumor but the lesion occurred soon after a severe bronchial asthma attack. Causal relation between spiny keratoderma of the palms and soles and bronchial asthma is obscure. Since this disease has been under-diagnosed and under-reported, it is important for dermatologists to keep spiny keratoderma of the palms and soles in mind in daily clinical examinations.- - - - - - - - - - ranking = 8keywords = palm (Clic here for more details about this article) |
7/65. Keratosis lichenoides chronica. Report of a case associated with B-cell lymphoma and leg panniculitis.Keratosis lichenoides chronica (KLC) is a rare chronic dermatosis characterized by lichenoid hyperkeratotic papules arranged in a linear and reticular pattern, and seborrheic-dermatitis-like lesions on the face. Less frequently, palmoplantar keratoderma, nail dystrophies, mucosal as well as eye lesions are present. KLC affects adults and very few cases have been reported in childhood. Although infrequently, KLC has been associated with systemic diseases, including chronic infectious diseases, kidney disorders and lymphoma. Here we report the case of an adult KLC patient with skin, nail and mucosal involvement, and onset in the first year of life who developed a leg panniculitis and a mantle cell lymphoma. Following chemotherapy for the lymphoma, panniculitis resolved completely, and skin and mucosal KLC lesions ameliorated.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
8/65. Keratosis lichenoides chronica: report of a case developing after erythroderma.A 66-year-old male presented with keratosis lichenoides chronica after a presumed drug-induced erythroderma. After resolution of the erythroderma, slightly scaly erythematous and violaceous papules in a reticular arrangement over the trunk and limbs developed in association with hoarseness, palmoplantar keratoderma, onycholysis and subungual keratosis. histology from a lichenoid lesion showed pseudo-epitheliomatous hyperplasia, hyperorthokeratosis, parakeratosis, dyskeratosis, neutrophil exocytosis and focal vacuolar degeneration of the basal layer of the epidermis. There was a band-like chronic inflammatory infiltrate in the upper dermis. The skin improved with prednisone 40 mg/day for 15 days, leaving atrophic hypopigmented scars. A diagnosis of keratosis lichenoides chronica was made.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
9/65. Collagenous and elastotic marginal plaques of the hands.A 49-year-old woman presented with an asymptomatic indurated linear plaque extending from the medial surface of the right thumb along the junction of the dorsal and palmar skin of the hand onto the lateral aspect of the index finger. The left hand showed a similar but less extensive plaque. A skin biopsy showed an acellular zone in the reticular dermis composed of thickened bundles of collagen haphazardly arranged, some perpendicular to the epidermis, admixed with elastic fibres and amorphous basophilic elastotic material. Granular calcium deposits were identified, particularly within degenerate collagen bundles. These clinical and histological features are diagnostic of collagenous and elastotic marginal plaques of the hands, a slowly progressive but largely asymptomatic condition. Actinic degeneration and chronic pressure have been proposed as aetiological agents, but our patient did not exhibit marked actinic degeneration and had no history of chronic occupational pressure.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
10/65. Olmsted syndrome: report of a case with study of the cellular proliferation in keratoderma.Olmsted syndrome is a rare disorder that consists of sharply marginated keratoderma of the palms and soles, constriction of digits and toes that may result in spontaneous amputation of the distal phalanges, hyperkeratotic plaques around the body orifices, onychodystrophy, and other less common cutaneous and extracutaneous anomalies. Although some patients had other affected family members, most cases of Olmsted syndrome seem to be of sporadic occurrence. We describe a patient with the characteristic features of Olmsted syndrome. The symptoms consisted of diffuse transgrediens palmoplantar keratoderma and keratotic plaques around the mouth and nose. Our patient also had the associated anomalies of hyperhidrosis of the palms and soles and congenital deaf-mutism. Histopathologic study of the keratoderma demonstrated epidermal hyperplasia with acanthosis, papillomatosis, and orthokeratotic hyperkeratosis.Immunohistochemical study showed more basal and suprabasal keratinocytes of the epidermis with immunoreactivity for Ki-67 marker when compared with the keratinocytes of the epidermis of the adjacent non-involved skin. These results support the notion that Olmsted syndrome is a hyperproliferative disorder of the epidermis.- - - - - - - - - - ranking = 3keywords = palm (Clic here for more details about this article) |
