Acanthosis palmaris in a patient with bullous pemphigoid.

Acanthosis palmaris, a recently described dermatologic entity, is often associated with internal malignancy. We report the development, disappearance, and reappearance of this condition in a patient with bullous pemphigoid. Relevant screening tests did not reveal any internal malignant neoplasm. The significance of the appearance and disappearance of the condition is discussed.

Dermatoglyphics in vitiligo.

One hundred probands of vitiligo were studied for palmar dermatoglyphics, both qualitatively and quantitatively, and were compared with those of 100 phenotypically normal control subjects. Ulnar loop pattern was the most common digital pattern observed in both probands and controls. An increased incidence of whorls and arches in men and women probands, respectively, was found to be statistically significant when compared with those of controls. Simian crease and Sydney line also have been observed in the present study, which has not been previously reported. A statistically highly significant reduction has been observed in total finger ridge count (TFRC) and a-b ridge count in both sexes of vitiligo cases when compared with those of controls. No significant changes was observed in the values of atd angle and position of axial triradius.

Palmar melanotic macules. A sign of neurofibromatosis.

Multiple melanotic macules of varying sizes were present on the palmar surfaces of 42 of 50 consecutive South Indian patients with von Recklinghausen's disease. The histologic characteristics of the macules showed localized areas of fingerlike prolongations of the rete ridges with increased pigmentation of the basal cells. This epidermal change overlies a small neurofibroma accompanied by thick-walled blood vessels in the reticular dermis. A clinicopathologic correlation of these palmar melanotic macules constitutes yet another frequent and specific marker of classical neurofibromatosis.
