Introduction: The trends of malignant melanoma in Brazil are aligned with those worldwide: increasing incidence with reduced degree of severity at diagnosis. Objective: To use the prognostic criteria of the Grupo Multicêntrico e Multidisciplinar Brasileiro para Estudo do Melanoma (Brazilian Multicenter and Multidisciplinary Group for the Study of Melanoma) combined with clinical characteristics aimed at developing a clinical and histopathological profile of melanoma cases. Methods: A cross-sectional descriptive study was carried out, with the retrospective analysis of medical records of patients diagnosed with melanoma at a tertiary dermatology reference unit in the city of Bauru, in the Brazilian southeast State of São Paulo, between January 2007 and July 2014. Results: Female patients accounted for 56.2%, with ages ranging from 27 to 95 years (Mean = 61.4 years), with a lesion having been detected on physical examination in 36% of cases. The highest incidence of the disease was in the lower limbs (23.5%), with the superficial spreading subtype corresponding to 79.6% of biopsies. The average Breslow thickness was 2.9 mm, and in 28.1% of cases, the lesion was in situ. Conclusions: The following profile emerged: women, 61-years-old, with lesions in the lower limbs, superficial spreading subtype and with evidence of good prognostic. Studies like this are important due to the fact they provide subsidies for the design of strategies to treat the population.

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.

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.
