Você conhece esta Síndrome

Brooke-Spiegler syndrome is an autosomal dominant inherited disease with predisposition to cutaneous adnexal neoplasms, most commonly cylindromas and trichoepitheliomas. Its onset is in the second or third decades of life. The histopathological exams of the lesions revealed a plethora of benign adnexal neoplasms, showing apocrine, follicular, and sebaceous differentiation. The treatment can be performed by excisional surgery, laser, cryotherapy, electrofulguration and dermabrasion. Due to the risk of malignancy, there is the need for clinical follow-up and genetic counseling.

Rabdomiossarcoma alveolar cutâneo primário em paciente pediátrico

Rhabdomyosarcoma is the most common soft tissue tumor in childhood; however, it rarely affects only the skin. This case report describes a child with a painful nodule on her face. Histopathology and immunohistochemistry confirmed the diagnosis of rhabdomyosarcoma, and a multidisciplinary team then followed up the patient. Soft tissue tumors are responsible for 6% of all childhood tumors, and 53% of these are rhabdomyosarcomas, which may affect any part of the body. Presentation in the form of skin nodules is rare and represents a diagnostic challenge, since there are no clinical characteristics that differentiate this condition from other pathologies.

Use of dermoscopy for diagnosis of exogenous ochronosis

Exogenous ochronosis consists of chronic hyperpigmentation of areas previously treated with topical agents such as hydroquinone, resorcinol, antimalarials and phenol. Early diagnosis allows to promptly suspend the causative agent and it is imperative since the available therapeutic options are scarce and have presented so far unsatisfactory results. Three cases of exogenous ochronosis on the face which were diagnosed with the use of dermoscopy are presented. Dermatoscopy showed blackish-gray amorphous structures, some obliterating the follicular openings. Histopathological examination confirmed the diagnosis.
