Thyroid cancer and Graves' disease may present simultaneously in one patient. The incidence of the development of hyperthyroidism from metastatic differentiated thyroid carcinoma is rare. We herein report a case of metastatic follicular carcinoma complicated with Graves' disease after total thyroidectomy. A 57-year-old woman underwent right hemithyroidectomy for follicular carcinoma. Metastatic...

Metastatic carcinoma that causes appendicitis is extremely rare. To our knowledge, metastatic cholangiocarcinoma in the appendix has been reported in only 1 case in the English literature. We report herein the case of an 87-year-old woman who presented with abdominal pain and jaundice. Advanced cholangiocellular carcinoma and a proximal appendiceal mass with appendicitis were detected on contra...

basal cell carcinoma (bcc) is the most common cancer among humans, and the standard treatment is surgery. other modalities are reserved as a second line of treatment. topical chemotherapy may be used in primary bcc. systemic chemotherapy has no role in the primary treatment of bcc, although it may be efficacious in metastatic cases. we report the case of a patient with persistent recurrent bcc ...

BACKGROUND We report an unusual case of a synchronous rectal and metachronous vaginal metastatic renal cell carcinoma. CASE PRESENTATION A 78-year-old woman presented with hematochezia and a colonoscopy revealed a metastatic clear-cell renal cell carcinoma rectal polyp biopsy-proven. Abdominal computed tomography identified a 9.0-cm left renal mass with renal vein thrombosis, for which she un...

The authors report a rare case of primary mucinous carcinoma of the skin initially diagnosed as a metastatic adenocarcinoma. The tumor occurred in the right axilla in a 75-year-old man. Initial pathological diagnosis was metastatic adenocarcinoma. However, no primary focus was found in the body. The revised diagnosis by the authors was primary cutaneous mucinous carcinoma. The tumor (1.5 cm) wa...

Twenty-one patients with medullary thyroid carcinoma were studied prospectively with Tc-99m (V) DMSA after surgery. Pentavalent DMSA scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. Finally, seven patients with surgical or other imaging documentation were selected for this paper. Most of these patients were asymptomatic. Six patients had hypercalcitonemia ...

Sinonasal region is an exceptional site for metastatic tumors. Renal cell carcinoma is known to metastasise to the most unusual sites, the sinonasal region being one of them. Clear cell carcinoma is its most common histologic variant. A sixty year old male presented with epistaxis and nasal obstruction. Clinical examination and CT scan revealed a vascular tumor in the right nasal cavity and max...

Cancer of unknown primary (CUP) is metastatic cancer without a clinically detectable defined tumor site after an adequate diagnostic evaluation. It well recognized that CUP incidence occupies 1-5% all malignant epithelial tumors. Herein, we report case peritoneal carcinoma diagnosed as revealed by laparoscopic surgery.

Basosquamous carcinoma (BSC) is a rare type of malignancy with features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) with a potential for aggressive behaviour infiltration and destruction. First reported by MacCormac in 1910 in a series of rodent ulcers, this entity does have an increased risk of recurrence and metastases as well, which distinguish it from other forms ...
