[Dowling-Degos disease].

We report two cases of Dowling-Degos' disease, one affecting the vulvovaginal semimucose, and one associated to a terminal malignant neoplasia. We remark the importance of this knowledge in order to distinguish it from malignant acanthosis nigricans or other patterns of melanosis or lentiginosis when located within mucose or semimucose, specially at the genitals. All cases associated to malignant neoplasia described are emphasized. However Dowling-Degos' disease is considered to be a nonparaneoplasic genodermatoses, this association should be taken into account.

Woolly-hair nevus: report of a case associated with a verrucous epidermal nevus in the same area.

We cared for a patient with woolly-hair nevus (WHN) with hair of reduced diameter seen as oval shaped on transverse section. Scanning electron microscopy revealed a longitudinal canal along the length of the hair shaft. Although the association of WHN and epidermal nevus has been described previously, this report of their localization in the same site is, to our knowledge, the first in the literature.

[Segmental neurofibromatosis].

Four cases of segmental neurofibromatosis (SNF) are reported. It is a rare entity considered to be a localized variant of neurofibromatosis (NF)-Riccardi's type V. Two cases are male and two female. The lesions are located to the head in a patient and the other three cases in the trunk. No family history nor transmission to progeny were manifested. The rest of the organs are undamaged.

Perforating pilomatricoma.

A case of perforating pilomatricoma is described. A few published cases have shared the following features: rapid development, reddish exophytic clinical appearance with surface alterations suggestive of perforation, relatively shallow location making contact with the epidermis, and the occurrence of transepithelial elimination phenomena.

Tubular apocrine adenoma.

We report a case of tubular apocrine adenoma located on the scalp, with characteristics of syringocystadenoma papilliferum in the superior part of the lesion. An interesting feature of the growth is its connective tissue involvement.

Autosomal dominant lamellar ichthyosis.

Five members of two generations of one family were affected with lamellar ichthyosis, suggesting autosomal dominant transmission. The clinical and histopathological characteristics of the cases described here are similar to those reported by Traupe et al. (1984) as autosomal dominant lamellar ichthyosis and thus confirm the existence of this new form of ichthyosis.

[Perforating necrobiosis lipoidica].

This is the case history of a woman with a 6 year history of insulin-dependent diabetes mellitus and a 5 year history of tuberous lesions on the dorsal aspect of the metacarpophalangeal joints. Histological examination revealed multiple necrobiotic foci throughout the dermis and subcutaneous tissue, with varying degrees of degeneration, alternating with fibrotic areas. This picture is compatible with lipoid necrobiosis. The existence of various foci of epithelial perforation, manifested clinically by a point hyperkeratosis similar in appearance to blackheads, suggests transfollicular elimination. This would explain the total absence of a pilosebaceous follicles in the lesion.

Adult↗

[Myoma of the breast muscle].

A female patient presented with a tumoral lesion of the areola of the left breast; the lesion surrounded the nipple. Histopathologically there was proliferation of smooth muscle fibers of the middle and deep layers of the dermis; the papillary dermis was not affected. Myomas in this site do not present the typical characteristics of other kinds of leiomyomas, including those of the scrotum. Therefore, mamillary muscle myomas should not be considered authentic tumors, but rather smooth muscle hyperplasias.

Chronic infection due to Fusarium oxysporum mimicking lupus vulgaris: case report and review of cutaneous involvement in fusariosis.

A 67-year-old female presented with a 20-year-old lesion involving the right ear and preauricular area mimicking tuberculous lupus. Fusarium oxysporum infection was confirmed by biopsy studies and cultures. The biopsy specimen showed an unusually extensive dermal invasion with fungal hyphae. This is an uncommon clinical presentation for Fusarium infection in a healthy patient. When referred to us, the patient had received antifungal therapy with itraconazole without any benefit. Improvement was obtained with fluconazole therapy. The spectrum of cutaneous involvement related to Fusarium spp. includes toxic reactions, colonization, superficial indolent infection, deep cutaneous or subcutaneous infections and disseminated infection.
