RESUMEN
An otherwise healthy 55-year-old female, nonsmoker, was seen in pulmonary consultation for progressively worsening shortness of breath. She had undergone a complete hysterectomy 7 years prior for bleeding leiomyomas. On presentation, her initial chest X-ray showed a large right-sided pleural effusion with multiple pulmonary nodules. Two thoracenteses failed to reveal any cytologic abnormalities. Bronchoscopy revealed smooth, round, endobronchial lesions. Histologic examination showed features consistent with leiomyosarcoma. We present a rare case of a patient that initially had possible leiomyomas of the uterus surgically removed and years later presented with bronchopulmonary leiomyosarcoma.
RESUMEN
Signet ring cell carcinoma (SRCC) is a subtype of adenocarcinoma. It can arise in different organs including stomach, colon, bladder, prostate and breast. The vast majority of SRCC found in the pulmonary system is metastatic. Primary disease to the lungs is rare. The main feature of this type of malignancy is mucin-producing cells. It has been reported that out of 3500 cases of pulmonary adenocarcinoma, five cases had features of SRCC.
