A Case of Infantile Nephrotic Syndrome with Focal Segmental Glomerulosclerosis

Paraganglioma is a benign tumor arising in the paraganglion system scattered throughout the body, but its cytopathologic findings arenot well known. We experienced a case of paraganglioma of carotid body diagnosed by fine needle aspiration. The patient was a 30 year-old female who suffered from the left neck mass for 3 years. The mass was 3x3crn in size without pulsation or bruit. Cytologically, the smear revealed aggregated and singly scattered tumor cells having abundant pale cytoplasm and indistinct cell borders. Their nuclei were round to oval, but enlarged nuclei were occasionally observed. The nuclear membrane was smooth with fine clumping of chromatin. Differentiation from metastatic follicular carcinoma of the thyroid gland was difficult.

Cutaneous Metastasis of Pancreatic Carcinoma by Percutaneous Fine Needle Aspiration Biopsy

The cutaneous metastasis of pancreatic carcinoma by this technique is rarely reported in the literature. A 67-year-old woman was evaluated for left-sided abdominal pain and a palpable abdominal mass. Abdominal CT confirmed the presence of a solid mass involving the pancreas. Ultrasonically guided percutaneous aspiration biopsy was performed. About six month later, the patient was readmitted with a tender tumor mass at the site of the previous aspiration biopsy. Physical examination disclosed a 4 × 4 cm sized firm, tender tumor mass on the abdomen. Histopathological findings of the tumor mass are consistent with metasta tic lesions from a pancreatic carcinoma. We report a case that suggests cutaneous metastsis of pancreatic carcinoma by fine needle aspiration biopsy.
