Eosinophilic pancreatic infiltration as a manifestation of lung carcinoma.

A 68-year-old man reported upper abdominal pain during the previous 3 months that worsened in the last 2 days. He had a history of lung squamous cell carcinoma for which he underwent right lung lobectomy 3 years earlier. Preliminary blood tests showed leucocytosis with marked eosinophilia. No evidence of recurrent malignancy was detected, but computed tomography scan of the abdomen revealed an enlarged and edematous pancreas with hyperemia and infiltration of the peripancreatic fat. Fine needle aspiration from the lesion revealed inflammatory infiltration predominantly composed of eosinophils. The diagnosis of eosinophilic pancreatitis was suggested and the patient was placed on prednisone, but without any clinical or laboratory improvement. Two months later, the patient developed severe dyspnea, chylothorax, and acute renal failure. Cytologic studies of the pleural fluid revealed malignant cells from recurrent lung squamous cell carcinoma. The disease course was characterized by rapid deterioration and a fatal outcome. To the authors' knowledge, eosinophilic pancreatic infiltration as a manifestation of lung carcinoma has not been previously reported.

Combined adrenal myelolipoma and medullary hyperplasia.

OBJECTIVE: A patient is reported with hypertension due to combined medullary adrenal hyperplasia and myelolipoma. METHODS: A 52-year-old woman with long-standing hypertension was evaluated for an incidentally discovered large tumor of the left adrenal. Left adrenalectomy was performed for a presumptive clinical diagnosis of pheochromocytoma. RESULTS: Histopathologic examination revealed a mixed tumor consisting of a large myelolipoma with infiltrating foci of adrenal medulla. CONCLUSIONS: A patient is described with hypertension, myelolipoma and adrenal medullary hyperplasia; following adrenalectomy, however, blood pressure and biochemical abnormalities normalized.

Mixed follicular-medullary thyroid carcinoma: a case report.

We report on a 35-yr-old woman presenting with a single thyroid nodule. Fine-needle aspiration (FNA) of the nodule was reported to contain both follicular and parafollicular cells. The biphasic nature of the tumor was highlighted on immunohistochemical investigation of the cellblock. Positive staining for thyroglobulin was limited to the follicular structures and the dense areas stained positive for calcitonin. The serum calcitonin level was highly elevated. Surgery was recommended because of suspected malignancy. The patient underwent total thyroidectomy. The diagnosis of mixed medullary and follicular carcinoma of the thyroid was established by histological investigation using immunohistochemical staining for thyroglobulin, chromogranin, and calcitonin. The patient was well 1 yr after the operation. Repeated measurements of serum calcitonin levels were normal. Total body scan revealed no radioactive iodine uptake in the thyroid bed, bones, or lungs.

Metastatic minor salivary gland colloid carcinoma in the parotid region after parotidectomy for pleomorphic adenoma: a case report.

BACKGROUND: Primary colloid or mucinous carcinoma of the salivary glands is extremely rare. Only a few cases have been reported that originated in the minor salivary glands. an even more exceptional presentation is as a metastatic tumor in the parotid region subsequent to superficial parotidectomy for pleomorphic adenoma. The case presented here posed a diagnostic dilemma that could be resolved only after a thorough reevaluation of the previous cytologic and histologic material and detection of the occult primary tumor in the hypopharynx following an extensive clinical and radiologic workup. CASE: A 75-year-old female underwent fine needle aspiration of the left parotid and was diagnosed as having pleomorphic adenoma. A superficial parotidectomy removed the tumor completely, and the diagnosis was confirmed. Six months following the surgery, the patient developed an enlarged nodular mass in the ipsilateral parotid region, with fine needle aspiration showing colloid (mucinous) adenocarcinoma, which proved to be a metastatic colloid (mucinous) carcinoma on excisional biopsy. The clinical and radiologic workup in search of a primary lesion led to an occult tumor in the left hypopharyngeal mucosa. CONCLUSION: Unusual presentations of rare tumors can cause considerable diagnostic difficulties to both the clinician and cytopathologist. Awareness of these rarities is important to ensure the best patient care and to avoid unnecessary investigative and therapeutic procedures.
