RESUMO
We describe three cases of polyarteritis nodosa cutanea (PNC) showing necrotizing arteritis and only cutaneous lesions without systemic symptoms or visceral involvement for eleven, six, and three years after the onset of the disease. Since it was first described, there has been continuous controversy as to whether PNC progresses to systemic PN. Some cases have been described which had begun with a cutaneous lesion and progressed to the systemic form 19 and 18 years after the onset of the disease, so we believe that long term follow-up of this disease is essential.

Topical PUVA therapy was applied to a patient with localized scleroderma. Her localized scleroderma responded very well to the topical PUVA therapy, i.e., her sclerotic skin softened to normal skin texture. However, despite this dramatic clinical change the histopathological findings did not change at all and were still "hard".

Mobile encapsulated lipoma, first described by Sahl in 1978 (1), is characterized by its great mobility within subcutaneous adipose tissue and presentation with or without tenderness when the nodules are manipulated. This lipoma's histopathology is very characteristic; i.e., it consists of mature viable or degenerative lipocytes encapsulated by fibrous tissue. We report a case of this so-called mobile encapsulated lipoma involving a patient with Ehlers-Danlos syndrome. This case is the first report of mobile encapsulated lipoma in a patient with a disease of this type. We discuss its pathogenesis and the nomenclature for these lesions.

Pemphigus foliaceus (PF) is most commonly observed on the face, scalp, chest and back at the onset of the condition. The case described here is that of an 81-year-old female with a single PF lesion localized to the right cheek. A review of the literature published in English and Japanese disclosed only 3 cases of PF in which the patient presented with a single lesion, and 2 of these cases were referred to as "localized pemphigus foliaceus".
