We report a peculiar case in an 80-year-old man with multiple bone metastases due to the recurrence of thymic carcinoid tumor after surgical resection and radiation therapy ten years earlier. He was admitted to our hospital with a complaint of lumbago. Fluoro-2-deoxy-D-glucose (FDG) PET was useful for recognition of multiple bone metastases due to the recurrence of thymic carcinoid tumor, while...

The synchronous occurrence of pulmonary tuberculosis and bronchial carcinoid tumor is unusual.

We present coexistent bronchial carcinoid tumor and pulmonary tuberculosis in the same lobe. A 39-year-old woman was ...

We present clinicopathological and cytological findings of a well-defined breast mass in a patient with history of primary renal carcinoid tumor. Fine-needle aspiration (FNA) cytology showed monotonous tumor cells with plasmacytoid appearance arranged singly and in small clusters. Occasional tumor cells were arranged in acinar architecture resembling glandular differentiation. Tumor cells showe...

Neuroendocrine carcinomas of the larynx include a range of rare tumors which have variable biologic behavior, affecting treatment and prognosis. Among these, typical carcinoid tumors are the least common type. Prognosis of typical carcinoid tumor is better than atypical carcinoid tumor and small cell carcinoma of the larynx. Conservation surgery is the preferred treatment modality. Transoral CO...

The appendix is one of the most common sites for carcinoid tumors. Most carcinoids are found in appendices removed incidentally at laparotomy for conditions unrelated to acute appendicitis. We describe the case of a 13-year-old female who presented with abdominal pain in the right lower quadrant (RLQ), with nausea and decreased appetite for the previous 2 days. A physical examination favoreda d...

The patient was a 59-year-old man who presented with lower urinary tract symptoms. His biopsy specimen demonstrated a high-grade prostatic adenocarcin...
