[Brooke-Spiegler syndrome: an heterogeneous entity].

The Brooke-Spiegler syndrome is a rare, autosomally dominant disease with a predisposition to develop different adnexal tumors. Clinically it is characterized by the presence of multiple cylindromas, trichoepitheliomas, and occasionally, spiradenomas. Although Brooke-Spiegler syndrome, familial cylindromatosis and multiple familial trichoepithelioma were initially described as separate entities, the recently identified identical mutations in the gene of cylindromatosis suggest that they represent fenotypic variations of the same entity. In this article we present the case of a woman and her daughter, both affected by this rare genodermatosis.

Cutaneous sarcoidosis and polycythemia vera.

Polycythemia vera is classified with myelogenous leukaemia, agnogenic myeloid metaplasia and primary thrombocythemia as a myeloproliferative syndrome. Cutaneous symptoms have been reported with polycythemia vera, including facial plethora, aquagenic pruritus, urticaria, purpura, Sweet's syndrome and pyoderma gangrenosum. However, polycythemia vera associated with systemic sarcoidosis has been rarely reported. An unusual case of polycythemia vera associated with cutaneous sarcoidosis is described.

Relapsing cutaneous alternariosis in a kidney transplant recipient cured with liposomal amphotericin B.

An immunosuppressed patient who presented with unusual clinical signs of cutaneous alternariosis, including papular, nodular and verrucous lesions of the forearms, is reported. In spite of continuous treatment with oral itraconazole for 6 months, a large, progressive, necrotic ulcer appeared on the patient's left leg. Liposomal amphotericin B was then administered (total dose, 750 mg) with excellent clinical results.

Merkel cell tumor presenting as a painful patch lesion on the right arm.

Primary small cell cutaneous neuroendocrine carcinoma (Merkel cell carcinoma) is an uncommon, highly malignant, primary cutaneous neuroendocrine carcinoma. Clinically it is seen as a 0.5- to 5.0-cm pinkish purple papule or nodule, usually not ulcerated, on the head, neck, or, less frequently, the roots of the limbs. We present the case of a woman with an atypical clinical presentation of a Merkel cell tumor.

The association between idiopathic scoliosis and the number of acquired melanocytic nevi.

BACKGROUND: Several syndromes in which melanocytic nevi and scoliosis were present in the same patient have been described. No control study has been made to date to determine whether there is a relationship between these disorders. OBJECTIVE: We attempted to demonstrate the association between acquired melanocytic nevi (AMN) and idiopathic scoliosis (IS). METHODS: We studied 93 patients with IS, aged 10 to 18 years, from our hospital. Controls were randomly selected from 2 schools; Adam's forward bending test was used to exclude persons with clinical scoliosis, and the control group finally comprised 101 pupils. An observational, cross-sectional study was done. All AMN 2 mm or larger observed on the body were counted by one dermatologist. Other variables reported as risk factors in the number of nevi were also considered. Reliability of AMN counts was previously demonstrated. RESULTS: The median number of AMN was 18 (range, 10-42) in the IS group and 8 (range, 3-13) in controls (P <.001). The persons with scoliosis had more non-AMN dermatologic lesions than the controls (P <.05). Light phenotype correlated with many AMN. On multivariate analysis only scoliosis and age accounted independently for the number of AMN. CONCLUSION: IS is associated with many AMN. Multiple AMN may become a diagnostic marker for IS, and these two malformations might constitute a syndromic association.

Mucinous metaplasia of apocrine duct.

Mucinous syringometaplasia is a rare condition characterized by the presence of mucinous cells lining eccrine ducts. Because most occurrences are on the palms and soles, the disorder is generally considered to be the result of chronic trauma or pressure. We describe an example of mucinous metaplasia involving an apocrine duct on the left arm of a 57-year-old woman. Histopathologic study demonstrated that in deeper areas of the invagination, the lining of the lumen consisted of columnar cells showing decapitation secretion and that the invagination was connected to a rudimentary hair follicle. These histopathologic features support the possibility that the involved duct was an apocrine one. We discuss the differential diagnosis with those cutaneous adnexal neoplasms in which the presence of mucinous cells has been described.

Segmental arrangement of multiple, partly congenital and partly acquired melanocytic nevi.

A 15 year-old girl presented with numerous congenital melanocytic nevi, occasionally hairy, with a segmental distribution at the left pre-auricular region. On the left side of the back of the neck there were multiple melanocytic nevi with a warty appearance, which had started to appear when she was 5 and which had remained stable from the time she was 10. These lesions had a distribution reminiscent of an epidermal nevus with a pattern similar to Blaschko's lines. On general physical examination there was a moderate degree of idiopathic scoliosis, with a left lumbar curvature. Biopsies were taken from both types of nevus which were diagnosed as congenital compound melanocytic nevus and acquired compound melanocytic nevus respectively. We consider that the segmental distribution of the melanocytic nevi of this patient supports the theory that a genetic defect determined the appearance of both these congenital and acquired lesions.
