Frontal fibrosing alopecia versus lichen planopilaris: a clinicopathological study.

BACKGROUND: Frontal fibrosing alopecia (FFA) is an acquired scarring alopecia currently considered a clinical variant of lichen planopilaris (LPP). Our purpose was to examine the clinicopathological features of FFA. In addition, we investigated the similarities and differences between FFA and LPP. METHODS: Biopsies from the scalp lesions of eight patients with FFA and eight patients with LPP were microscopically analyzed. Two cases of FFA and four cases of LPP were studied using direct immunofluorescence. RESULTS: In spite of the completely different clinical characteristics of FFA and LPP patients, the histopathological findings for the two entities were similar. Common microscopic findings for both FFA and LPP included an inflammatory lymphocytic infiltrate involving the isthmus and infundibulum of the hair follicles, the presence of apoptotic cells in the external root sheath, and a concentric fibrosis surrounding the hair follicles that resulted in their destruction with subsequent scarring alopecia. Biopsies taken from FFA patients showed less follicular inflammation and more apoptotic cells than those from LPP patients. In some cases of LPP, the inflammatory infiltrate involved the interfollicular epidermis, a finding never present in our FFA cases. Direct immunofluorescence was negative in the two cases of FFA studied and showed deposits of immunoglobulins and/or complement in two of the four LPP cases examined. CONCLUSIONS: The characteristic findings for FFA were more prominent apoptosis and less inflammation than found in LPP, along with spared interfollicular epidermis. FFA cases showed a rather characteristic histopathological pattern, although we could not find any clear-cut histological differences between FFA and LPP.

[Segmental anhidrosis associated with Adie's pupil: an incomplete case of Ross syndrome].

We present the case of a 43-year-old woman who presented with a localized area of anhidrosis on the upper left trunk and ipsilateral upper limb. It was associated with Adie's tonic pupil and an area of compensatory hyperhidrosis on the contralateral side. After 9 years of follow up, the alterations have remained stable. These alterations of the autonomous nervous system correspond to an incompletely expressed Ross syndrome.

[Hyperkeratotic vascular malformations. Presentation of three cases].

Hyperkeratotic vascular malformations (verrucous hemangiomas) are infrequent vascular lesions present from birth. Initially, they are reminiscent of port wine stains or childhood hemangioma, but over time they gradually take on their typical warty and hyperkeratotic appearance. These changes are probably due to trauma, scratching and bleeding episodes. Because the lesion is deep and goes beyond the clinical lesion, treatment is difficult and involves many recurrences. We present three cases of this vascular malformation, in two males aged 45 and 62 and a 30-year-old female. All three had the lesion from birth, and presented with frequent bleeding episodes.

Leukocytoclastic vasculitis presenting as an erythema gyratum repens--like eruption on a patient with systemic lupus erythematosus.

Cutaneous leukocytoclastic vasculitis is a common finding among patients with systemic lupus erythematosus, although the clinical appearance of the lesions varies. We report the case of a 38-year-old woman with systemic lupus erythematosus who had leukocytoclastic vasculitis with peculiar clinical morphologic features of the cutaneous lesions. They consisted of figured erythema closely resembling erythema gyratum repens. We discuss the differential diagnosis with other annular eruptions.

[Study of dermatophytoses in Lanzarote (1995-199)].

We report on the incidence of dermatophytes isolated in Lanzarote island from June-95 to December-99. We gathered 76 samples. Tinea corporis was the most frequent (40.79%) condition, and after this, tinea pedis (26.31%). Trichophyton rubrum was the commonest agent isolated involving 52.63% of patients. We compare our results with other canarian studies, and with clinical patterns described in other spanish studies published in the 1990's. From these comparations we can deduce: a) The distribution of clinical pictures is not homogeneous among the papers, b) tinea corporis etiology is heterogeneous among the series and c) tinea pedis etiology is homogeneous in most of studies. We believe that the comparison by clinical forms avoids any bias due to distribution of clinical forms.

[Umbilical cutaneous endometriosis associated with a large uterine myoma].

We present a 44-year-old female patient who was being studied by the Gynecology Department because of the presence of large abdominal masses which proved to be leiomyomas on histological analysis. The Dermatology Department was consulted because of an asymptomatic umbilical tumor which had been developing for 5 years. Upon histological examination, we observed glands with angular lumens that showed decapitation secretion distributed throughout the dermis, surrounded by a cellular stroma with extravasated erythrocytes.
