Lichen sclerosus is an uncommon condition affecting both the genital and extragenital region, the latter constituting an atypical occurrence of the disorder. The use of topical corticosteroids is considered the first-line treatment of this genital disease. Extragenital lesions are less sensitive to this therapy. The present study describes a case of lichen sclerosus in an 82-year-old female patient, with widespread extragenital involvement and successful treatment with narrow band UVB phototherapy. Lichen sclerosus is a chronic inflammatory dermatosis and disseminated forms of the condition are rare, with an absence of consensus on the treatment of the extragenital form. The choice for narrow band UVB therapy was based on the literature.

Introduction: Glomus tumor is a benign and rare neoplasm that appears as solitary and painful nodule, mainly subungual. It presents characteristic clinical manifestations such as paroxysmal pain and sensitivity to local pressure and to cold.
Objective: To conduct a clinical epidemiological survey of glomus tumors diagnosed in a reference unit in 16 years.
Methods: Retrospective study assessing clinical and epidemiological data of 15 patients with glomus tumor confirmed by histopathological report from 2000 to 2016. Data on age, gender, tumor location, associated symptoms, duration of symptoms until diagnosis, clinical presentation, histological type and recurrence after surgery were analysed.
Results: Fifteen cases were diagnosed, 11 in women (73.3%) and four in men (26.7%). Mean age was 63 years. The most frequent location was the subungual region. Mean duration of symptoms until diagnosis was 8 years.
Conclusions: In this study, the number of cases of glomus tumor fluctuated throughout these 16 years, with a mean of 0.9 cases/year. A higher prevalence in women over 60 years, subungual region location and solid glomus histologic subtype was observed.

The Merkel cell carcinoma is a rare and highly aggressive neuroendocrine skin tumor. The purpose of this paper is to warn of the possibility of this diagnosis, usually not considered as an initial hypothesis in cutaneous neoplasias. The authors describe two cases of elderly female patients with complaints of a single erythematous nodule on the face. The diagnoses of basal cell carcinoma and amelanotic melanoma were considered. The presence of telangiectasias was evident at dermoscopy. The incisional biopsy's histology evidenced Merkel cell carcinomas. This neoplasia typically occurs in Caucasian patients with over 65 years of age, emerging as an erythematous-purplish nodule of rapid growth, with immunohistochemistry being essential for the diagnosis.

Cutaneous metastases of internal malignancy are rare, and their incidence ranges from 0.7 to 9% among all cancers. They account for 2% of all skin tumors. They occur due to the growth of cancer cells in the dermis or subcutaneous cellular tissue, originating from internal neoplasia. Cutaneous metastasis arising from squamous cell carcinoma of the esophagus is rare, accounting for less than 1% of cases. We report a case of squamous cell carcinoma of the esophagus diagnosed after metastatic cutaneous manifestation in the abdomen that evolved to death due to disseminated metastatic tumor invasion.

Lichen planopilaris is a rare disorder that belongs to the primary scarring alopecia type. The present study describes the case of a female patient bearing desquamative erythematous plaques and follicular plugs bilaterally in the frontoparietal region, associated with positive pull test. The biopsy's result was consistent with lichen planopilaris and the patient was treated with prednisone associated with clobetasol, with regrowth of the hair in the affected area. The treatment of this pathology is a challenge due to the lack of data on efficacy of therapies and constant recurrence. The picture is irreversible if not treated early. This paper describes a classic case of a case of lichen planopilaris with good therapeutic response, highlighting the importance of early diagnosis, due to the fact that most cicatricial alopecias do not produce scarring in their initial stage and should for this reason be managed as an emergency in trichology.
