A case of pigmented basocellular carcinoma clinically mimicking a malignant lentigo melanoma in the temporal region of a black female patient is reported. Basal cell carcinoma rarely occurs in black patients. When present, however, it is the second most common malignant skin neoplasia, and is usually pigmented. When the face is affected in such patients, it is difficult to differentiate between malignant lentigo melanoma and basal cell carcinoma. Dermatoscopy is a very helpful diagnostic tool in these cases.

Pyogenic granuloma is a common vascular proliferation that can be found on skin and mucous membranes. Its clinical presentation is that of a nodular, friable and erythematous lesion, with fast growth history. The nail bed pyogenic granuloma is generally related to onychocryptosis and trauma, being very painful in that site. There are several treatment options, including surgical excision, cryotherapy, electrocautery, curettage, lasers, application of trichloroacetic acid, imiquimod and microembolization. The present study reports a case of bilateral pyogenic granuloma in the halluces with exuberant growth, leading to the occlusion of the nail plate. The surgical excision of the lesion was performed with good cosmetic results.

The upper lip is commonly affected by cutaneous carcinomas. The excision of the neoplasia with safe oncologic margins calls for a large incision, and sometimes flaps are necessary. In addition to its aesthetic value, a successful lip reconstruction includes the maintenance of perfect oral functionality. The authors describe a nasolabial rotation cutaneous flap associated with an advancement flap of the oral mucosa in a single surgical event, performed on a patient bearing basal cell carcinoma involving the left side portion of the upper lip.

The skin flaps are surgical techniques particularly useful to aesthetic repair in cases of extended excision and/or unusual sites, as in the ear. Many skin flaps options were already reported, resulting in variable results of the theoretical knowledge and practical experience of the surgeon. This article aims to describe two successful cases of ear reconstruction with the use of anterior and posterior flaps and to review the current literature.

Nodular hidradenoma is a benign adnexal neoplasia. Recently a subdivision in two groups has been suggested: tumors with eccrine differentiation or poroid hidradenoma and tumors with apocrine differentiation or clear cell hidradenoma. They present as well delimited dermal nodule, with a variable dimension between 0.5 and 3 cm, asymptomatic, slow growing and endophytic. Histopathology shows typical biphasic cell pattern, with polyhedral cells with eosinophilic cytoplasm and large cells with abundant clear cytoplasm and small nucleus. Malignant transformation is rare. We report a case of clear cell hidradenoma with unusual clinical characteristics and a review of the literature.

Hidradenitis suppurativa is a chronic inflammatory, recurrent and debilitating skin disease. Its etiopathogenesis involves follicular occlusion and genetic, environmental and immunological factors. Diagnosis is predominantly clinical, and the therapeutic approach is a major challenge due to its impact on the patient's quality of life. The surgical option is the most indicated in severe cases, nevertheless there is no consensus on the ideal treatment, as outcomes are diverse, and the aesthetic aspect after the procedure is generally unfavorable. This article was aimed at reporting a surgical option with primary wound closure, whose aesthetic result was superior to those derived from traditional techniques.

Non-melanoma skin cancer is the most common type of neoplasia. Basal cell carcinoma is the most common cancer of them, the incidence of which is steadily increasing, implying an important public and financial health issue. The authors present the case of a patient with an extensive basal cell carcinoma affecting part of the external auditory canal and auricular concha, treated with a combination of surgical techniques: flap-plasty associated with second intention closure of the external auditory canal. Due to the excellent aesthetic and functional outcomes, this technique should be considered as a therapeutic option for auricular lesions.

Non-melanoma skin cancer is the most common neoplasia in humans, and basal cell carcinomas (BCC) account for approximately 80% of cases. Cumulative exposure to ultraviolet radiation (UV) is the main risk factor associated to BCC, with a higher incidence in photoexposed areas, including the auricular region. The auricular region is a noble cosmetic unit, with anatomical peculiarities that lead surgeries to require the excision of a large amount of tissue, presenting a challenge for the dermatological surgeon. The authors present a case of helix reconstruction with a triple transposition flap.

INTRODUCTION: Dermatofibrosarcoma protuberans (DFSP) is a local aggressive sarcoma that presents 60% of recurrences. Rarely it presents lung metastasis too.
METHODS: 41 years old man presented a soft tumor in his right hallux for two years. Histopathology has shown spindle-shaped cells arranged in a storiform manner, and immunohistochemistry was CD34 positive.
DISCUSSION: The literature describes some clinical types of DFSP. The most common are: confluent nodules forming a plaque, sometimes similar to keloids, tumoral lesions, and atrophic plaques.
CONCLUSION: DFSP cases simulating a subcutaneous cyst have been described in the literature; nevertheless, it is an unusual presentation of this tumor.

Facial surgeries are often challenging for surgeons due to their complex anatomy, aesthetic and functional importance. Interventions in the cosmetic subunit that comprises the eyebrows can be particularly difficult. This case report aims to demonstrate the use of island flap in this region. We performed the excision of melanocytic nevus, with a good outcome and absence of postoperative complications. This technique is commonly used for facial reconstruction; however, the literature describes only a few cases using this method for eyebrow reconstruction.
