Subcutaneous abscess due to gallstones lost during laparoscopic cholecystectomy.

No complications caused by gallstones lost during laparoscopic cholecystectomy have yet been described in the literature. In one animal study in rats, it has been shown that pigment calculi, but not cholesterol stones, lead to severe local inflammation of the abdominal cavity. We present a case of a chronic subcutaneous and subfascial abscess in the lower abdomen, which included multiple pigment calculi, six months after laparoscopic cholecystectomy.

Fine needle aspiration cytodiagnosis of subacute (de Quervain's) thyroiditis in an endemic goitre area.

Between 1977 and 1989 252 fine needle aspirates (FNAs) of the thyroid from patients with a clinical suspicion of subacute granulomatous (de Quervain's) thyroiditis were examined in the Department of Pathology of the University of Innsbruck, Austria. In the same period 31 cases with preoperative FNA were diagnosed histologically as subacute thyroiditis. Only in three of these cases were the cytological features of de Quervain's thyroiditis found in the preoperative FNA.

Immunohistochemical comparison of chromogranins A and B and secretogranin II with calcitonin and calcitonin gene-related peptide expression in normal, hyperplastic and neoplastic C-cells of the human thyroid.

Normal and hyperplastic thyroid C-cells and 14 cases of medullary thyroid carcinoma were investigated immunohistochemically with antibodies against chromogranins A and B, secretogranin II, calcitonin and calcitonin gene-related peptide (CGRP). Normal and hyperplastic C-cells showed strong calcitonin and chromogranin A immunoreactivity whereas CGRP, chromogranin B and secretogranin II expression was less intense. Strong calcitonin and chromogranin A immunoreactivity was also found in the majority of tumour cells in medullary thyroid carcinoma.
