Mycosis fungoides palmaris et plantaris.

BACKGROUND: Mycosis fungoides primarily localized to the palms and soles is rare and has been previously reported as cutaneous lymphoma in four patients or as Woringer-Kolopp disease in eight patients. OBSERVATIONS: Four patients were initially diagnosed and treated unsuccessfully for various palmoplantar dermatitides until histopathologic findings revealed mycosis fungoides. Each case exhibited a clonal rearrangement of T-cell receptor gamma genes and immunohistochemical studies consonant with mycosis fungoides. All patients had limited skin involvement without evidence of extracutaneous involvement. CONCLUSIONS: Mycosis fungoides palmaris et plantaris is an uncommon expression of mycosis fungoides that manifests primarily on the palms and soles and clinically may mimic various inflammatory palmoplantar dermatoses. A biopsy is recommended in the evaluation of recalcitrant palmoplantar dermatoses.

Acantholytic epidermolysis bullosa.

BACKGROUND: We describe a new variant of inherited epidermolysis bullosa and elucidate the clinical, histologic, and ultrastructural features of this condition. OBSERVATIONS: This form of epidermolysis bullosa displays an autosomal dominant inheritance pattern, is characterized by acral bullae, and histologically demonstrates suprabasal clefting with acantholysis. Ultrastructural findings are nonspecific but reminiscent of those observed in benign familial pemphigus. CONCLUSION: Acantholytic epidermolysis bullosa is a rare but distinct clinicopathologic entity that warrants inclusion in the nosologic classification of epidermolysis bullosa.

Immediate and delayed skin allergy from cow dander.

BACKGROUND: Cow dander is the most common cause of occupational contact urticaria in Finland. Occasionally cow dander also causes allergic contact dermatitis, which can be revealed by patch testing with cow dander. OBJECTIVE: A patient with a combined type I and type IV allergy to cow dander is the subject of this report. RESULTS: She had intense pruritus, whealing, and severe dermatitis, but no respiratory symptoms. Skin tests and radioallergosorbent test indicated that she had both type I and type IV allergy to cow dander. CONCLUSION: Increasing numbers of cases with both type I and type IV allergy are reported, but the mechanism is not clear. In our clinic, we classify immediate reactions as contact urticaria if the clinical picture involves whealing, and as protein contact dermatitis if dermatitis dominates the clinical picture. If delayed allergic patch test results are obtained, we consider it allergic contact dermatitis.
