Duodenal somatostatinoma of the ampulla of vater diagnosed by endoscopic fine needle aspiration biopsy: a case report.

BACKGROUND: Duodenal somatostatinoma is a rare neuroendocrine neoplasm. A better prognosis can be obtained if these tumors are resected at an early clinical stage. Endoscopic punch biopsy has been the method most commonly used for the preoperative diagnosis of neuroendocrine duodenal tumors. To the best of our knowledge, endoscopic fine needle aspiration biopsy (FNAB) of duodenal somatostatinoma has not been reported before. CASE: A 41-year-old, black female presented with upper gastrointestinal bleeding as well as elevated bilirubin, liver enzymes and glucose. Computed tomography, esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP) detected a mass at the region of the ampulla of Vater partially obstructing the pancreatic duct. The initial punch biopsy yielded only intestinal mucosa. Subsequent endoscopic FNAB suggested the diagnosis of a neuroendocrine neoplasm, as confirmed by additional punch biopsies. Immunohistochemical and electron microscopic studies disclosed somatostatin production by the tumor, which was resected through a modified Whipple procedure. The patient recovered fully. CONCLUSION: This case demonstrates the usefulness of endoscopic FNAB in diagnosing submucosal gastrointestinal neuroendocrine tumors.

Nodular sarcoid myositis of skeletal muscle diagnosed by fine needle aspiration biopsy. A case report.

BACKGROUND: Symptomatic striated muscle involvement in sarcoidosis is rare. Muscle biopsy is usually required for the diagnosis. Fine needle aspiration biopsy (FNAB) has been successfully used in diagnosing soft tissue lesions. To the best of our knowledge, FNAB of sarcoid myositis has not been reported. CASE: A 31-year-old, black female with a history of sarcoidosis presented with an enlarging, painful, left calf mass. Infected thrombi were suspected. FNAB showed numerous loosely arranged epithelioid histiocytes, multinucleated giant cells and skeletal muscle cells. The overall cytologic picture was that of granulomatous myositis. The cytologic features coupled with the patient's history and magnetic resonance imaging findings suggested sarcoid myositis. Subsequent muscle biopsy showing noncaseating granulomata and negative stains for organisms confirmed the diagnosis of nodular sarcoid myositis. CONCLUSION: Nodular sarcoid myositis can be suggested by FNAB cytology in a patient with a past history of sarcoidosis.

Cytomorphology of tyrosine-rich crystalloids in fine needle aspirates of salivary gland adenomas.

OBJECTIVE: To evaluate the presence of tyrosine-rich crystalloids (TRC) in fine needle aspiration (FNA) specimens of pleomorphic adenomas of salivary gland. STUDY DESIGN: FNA specimens from 12 patients were reviewed, and the percentage of cases showing TRC was established. The staining properties of the TRC were evaluated as well as spontaneous fluorescence under ultraviolet (UV) light. RESULTS: Of the 12 pleomorphic adenomas, 4 showed TRC (30%) in the smears. Among the eight cytologically negative cases there were two that showed a few TRCs on histology. All positive cases were from African American patients. TRC stained weakly with Papanicolaou stain. TRC were deep blue with Diff-Quik. They fluoresced under UV light. CONCLUSION: TRC could be detected in FNA specimens. They were best seen under UV light. The Papanicolaou technique stained TRC very pale, making them difficult to see. Diff-Quik stained TRC dark blue, mimicking deposits of dye. The amount of TRC in histology paralleled the detection rate in cytology.

Bronchoalveolar lavage for diagnosis of fungal disease. Five years' experience in a southern United States rural area with many blastomycosis cases.

OBJECTIVE: To determine the relative frequency of Blastomyces dermatitidis among other microorganisms in bronchoalveolar lavage (BAL) specimens. STUDY DESIGN: The study group consisted of 208 BAL specimens received from 192 patients from March 1988 to August 1993. RESULTS: Forty-seven specimens from 42 patients were positive for pathogenic microorganisms, and 2 other specimens were diagnostic of malignancy. Pneumocystis carinii (23 specimens) was the most common microorganism found in the specimens. Candida spp (10 specimens) was the second most common microorganism, and B dermatitidis (5 specimens) was the third. Cryptococcus neoformans (3 patients), Histoplasma capsulatum (2 patients) and Conidiobolus coronatus (1 patient) were the other fungi detected in BAL. Acid-fast bacilli, cytomegalovirus and herpes simplex virus were also found (1 patient each). Several patients had more than one organism. CONCLUSION: B dermatitidis was the third most common microorganism found in BAL specimens at our hospital.

Spindle cell carcinoma of right lower alveolus. A case report.

A case report of spindle cell carcinoma of the right mandibular alveolus is reported, which clinically mimicked a squamous cell carcinoma. Careful histological interpretation is necessary for successful treatment of such tumors. The use of radiation therapy after radical neck dissection is also stressed upon.
