Pityriasis rotunda in a white patient. Report of the second case and review of the literature.

A 19-year-old white woman with pityriasis rotunda in whom no diagnosable disorder could be demonstrated is reported on herein. Pityriasis rotunda has been described in Oriental and black patients, usually in association with certain serious systemic diseases. Our patient appeared to have the second reported case of pityriasis rotunda in white persons. In both cases the dermatosis occurred in an otherwise healthy individual. Physicians should be alert to the possible occurrence of pityriasis rotunda in white patients. The literature on pityriasis rotunda is reviewed.

Prayer nodules in Moslem men.

Seven cases of Israeli Moslem men with hyperkeratotic nodular callosities of the legs and forehead are reported. These patients were randomly encountered over a two-year period in our dermatology clinic. The nodules were attributed to repeated trauma to the legs and forehead sustained during Moslem prayer. This article familiarizes the clinician with the morphologic characteristics of these lesions, which may occur in some Moslem men.

Perforating folliculitis in association with primary sclerosing cholangitis.

Two patients with primary sclerosing cholangitis developed perforating lesions in the skin of the extremities. Clinically and histologically, the cutaneous condition showed the features of perforating folliculitis with superimposed lesions of prurigo nodularis. The course of the eruption paralleled the severity of the biliary disease. A theory of pathogenesis for the development of the perforating folliculitis in these patients is suggested. To the best of our knowledge, this is the first report of the coexistence of both conditions.

Painful piezogenic pedal papules on a child with Ehlers-Danlos syndrome.

A 5-year-old girl with Ehlers-Danlos syndrome developed painful piezogenic pedal papules. She had suffered from pain in her heels for the previous two years and had undergone extensive orthopedic examinations that revealed no abnormalities. On admission, she had typical signs associated with piezogenic pedal papules (PPP), with pain induced by standing and disappearance of the lesions and the pain on relief of pressure. These papules were due to herniation of subcutaneous fat into the dermis, possibly because of structural defects of the connective tissue. To the best of our knowledge, this is the first reported case of painful PPP occurring in childhood. We suggest that the herniation of subcutaneous fat in our patient was most probably due to the connective tissue defect that occurs in the Ehlers-Danlos syndrome.

Transient acantholytic dermatosis occurring during pregnancy.

A case of transient acantholytic dermatosis (TAD) in pregnancy is reported. The eruption appeared in the third month of the pregnancy and completely resolved two months later. Reports concerning the occurrence of this disorder in young people are rare, and, to the best of our knowledge, this is the first patient in whom onset of the disease has been detected during pregnancy.
