RESUMO
Ectopic thymic tissue in the neck is rarely reported in medical literature. Being uncommon, they are rarely included in the clinical diagnosis of cervical cystic masses and are misdiagnosed by surgeons as branchial cysts, lymphatic malformations, epidermoid cysts, dermoid cysts or thyroglossal cysts, lymphadenitis or neoplastic masses. Although it is rare, cervical thymic cyst should be considered in the differential diagnosis of a lateral cystic neck mass. Here we report a rare case of thymic cyst in a young 15-year-old male child on the left side of the neck. Histopathology of the excised cyst revealed thymic tissue composed of prominent Hassall's corpuscles, cholesterol clefts, lymphoid aggregates and cyst lined by cuboidal and squamous cells.
RESUMO
Carcinoma en cuirasse is a form of cutaneous metastasis. Although this condition is rare, it is most commonly associated with breast carcinoma with local recurrence after mastectomy. Cutaneous metastasis presents most commonly a few months or years after the primary has been diagnosed. Less frequently a metastasis is diagnosed at the same time as the primary tumor or presents as the first manifestation of the disease. We report a case of carcinoma en cuirasse in a 50-year-old female who presented with elevated, finely nodular, indurated skin lesions on left anterior chest wall, axillary region and keloid - like patch on left upper arm. On further examination a breast mass was detected. Fine needle aspiration of all the lesions was performed. Cytodiagnosis was given as infiltrating duct carcinoma of breast with metastatic carcinoma involving left anterior chest wall, axilla and left upper arm. We should not disregard keloid-like or indurated patches on skin which should be investigated thoroughly.
