RESUMO
Abstract Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure.

Eccrine syringofibroadenoma is a rare benign adnexal neoplasm derived from cells of the acrosyringium of eccrine sweat glands. ESFA usually manifests as a solitary nodule on the extremities of elderly patients, but it may also present as papules, nodules or plaques. Its clinical appearance is nonspecific and malignant neoplasms should beconsidered in the differential diagnosis. However, histopathological findings are typical. The main treatment is surgical excision. In order to illustrate a typical presentation of the tumor, we report a case of solitary eccrine syringofibroadenoma, including the surgical treatment used and its result.

Erythema elevatum diutinum is a rare chronic cutaneous vasculitis which usually affects adults. It is characterized by symmetrical and persistent papules, plaques, and nodules. These lesions are usually located on the extensor surfaces of the extremities. We report a case of erythema elevatum diutinum in which the association of dapsone and surgical excision promoted complete remission of skin lesions, providing a new approach to the treatments described in the literature.
O eritema elevatum diutinum é uma vasculite cutânea rara, crônica, que costuma afetar adultos, manifestando-se com pápulas, placas e nódulos, simétricos e persistentes, nas regiões extensoras das extremidades. Relata-se um caso de eritema elevatum diutinum, onde a associação terapêutica da dapsona e excisão cirúrgica promoveu a remissão completa das lesões cutâneas, oferecendo uma nova abordagem aos tratamentos descritos na literatura.

As unhas podem ser acometidas em algumas doenças sistêmicas. Os autores examinaram 50 pacientes portadores de insuficiência renal crônica e constataram que unha "meio a meio" foi a mais freqüente alteraçäo e ocorrem em 32 por cento dos casos.
