Cisto cervical: maligno ou benigno? / Cervical cyst: malignant or benign?

Introdução: o carcinoma papilífero da tireóide pode apresentar-se a partir de uma metástase cervical. A presença de metástase cística cervical pode ser confundida com lesão benigna e postergar o tratamento adequado do carcinoma papilífero. Relato de caso: esse fato ocorreu com o caso apresentado o que nos trouxe ensinamentos. Trata-se de uma paciente jovem com lesão cervical cística há quatro anos, com ultra-sonografia compatível com lesão benigna. O exame histopatológico pós-operatório diagnosticou metástase de carcinoma papilífero de tireóide. Em nova ultrasonografia, duas imagens nodulares menores que 1cm foram observadas na glândula tireóide. Discussão: a dificuldade de diagnóstico clínico, por imagem e por punção aspirativa por agulha fina das lesões císticas pode postergar o diagnóstico e, com isso, o tratamento. O caso aqui apresentado nos alerta de que não devemos aceitar ultra-sonografia cervical que não contenha o estudo da glâdula tireóide, principalmente quando forem formações que possam sifnificar metástases.

Introduction: the thyroi papillary carcinoma can present itself as cervical metastasis. The presence of cystic cervical metastasis can be confused with benign lesions and delay the treatment of papillary carcinoma. Case report: it occurred in the present case. We are reporting a cse of a young female patient with a cystic cervical lesion for four years with ultrasonography (US) diagnostic compatible to a benign lesion. The patient underwent surgical resection and the histopathological analysis diagnosed metastasis of thyroid papillary carcinoma. Another US identified two nodes smaller than 1cm in the thyroid gland. Discussion: the difficulty of clinical and radiological diagnosis and the limitation of fine needle aspiration cytology of the cervical cystic lesions can delay the diagnosis and treatment. The cervical US without study of the thyroid cannot be accepted, specially when there is the possibility of a cervical metasasis.

Recurrent spontaneous breast hematoma: report of a case and review of the literature

BACKGROUND: Breast hematomas are common after traumas, surgeries, or contusions. They are rarely spontaneous, but they can occur spontaneously in patients with hematologic disease or with coagulation disorders. MATERIAL AND METHODS: The authors report a clinical case of a 48-year-old female with a 27-year history of paroxysmal nocturnal hemoglobinuria who underwent mammography screening because of a painless palpable moveable node in the upper inner quadrant of the right breast. RESULTS: Mammography showed a partially defined heterogeneous node of 35 mm without microcalcifications in the upper inner quadrant of the right breast which, associated with the clinical features, seemed to be an hematoma. Further mammography and ultrasound after 45 days showed retrocession of the lesion, and another mammography obtained after 60 days was normal. Seventy-five days after the first episode, the patient complained of another node with a skin bruise in the upper outer quadrant of the same breast, which seemed to be a recurrent hematoma. Two months later the mammography obtained was normal. CONCLUSION: Breast hematoma must be thought of as a differential diagnosis for a breast node, regardless of previous trauma or hematologic disorders
