Infarction of the gallbladder: a complication of hypertension. Case report.

A case of gallbladder infarction, occurring in a 34-year old man with severe hypertension is described, with uneventful recovery following cholecystectomy. In the absence of other obvious etiologic factors, the gallbladder infarction is presumed to be directly related to hypertensive vascular disease. Infarction of the gallbladder is rare; a few cases associated with hypertension have been previously reported. Other types of vascular disease including embolization, thrombosis complicating atherosclerosis and celiac angiography, polyarteritis nodosa, occlusion following torsion and cystic vein thrombosis have been reported to cause gallbladder infarction.

Mediastinal esophageal duplication cyst associated with a partial pericardial defect.

A two-year-old girl with a mediastinal esophageal duplication cyst is the twelfth example of a thoracic cyst of foregut origin or pulmonary "sequestration" (bronchopulmonary foregut malformation according to the expanded definition of Gerle et al.) that has been associated with a partial pericardial defect on the same side, suggesting that anomalous thoracic masses of several morphologic types have a similar pathogenesis.

Parosteal osteogenic sarcoma of the mandible, Existence masked by diffuse periodontal inflammation.

A 38-year-old man was in a state of poor oral hygiene, with multiple broken carious teeth and diffuse inflammatory hyperplasia of the gingival tissues. A mandibular, alveolar soft tissue mass in the premolar-molar region was noted on the right side, in continuity with the gingival hyperplasia. Biopsy of the lesion ruled out a diagnosis of squamous cell carcinoma. The patient underwent extraction of his teeth, and all hyperplastic tissues including the tumefaction were excised. Five months later, the patient had a recurrent mass in the same location that was removed via hemimandibulectomy. The mass was diagnosed as a parosteal osteogenic sarcoma.

Eccrine sweat gland tumor of clear cell origin involving the eyelids.

A 47-year-old patient with an unusual tumor involving the right upper and lower eyelids has been followed for almost 6 years. The tumor has remained localized to the eyelids and has recurred locally following attempts at complete or partial excision. The morphological features of the tumor as seen by ordinary light microscopic methods were puzzling, and resulted in a variety of pathologic diagnoses. Light microscopic examination of plastic-embedded semithin sections, and electron microscopic examination indicate that this is a hitherto undescribed eccrine sweat gland tumor of clear cell origin. Its infiltrative growth pattern and tendency to local recurrence suggests that it may be a low-grade malignant neoplasm.

Small cell epidermoid carcinoma of the esophagus. An oat-cell-like carcinoma.

A case of small cell anaplastic epidermoid carcinoma of the esophagus is reported. The morphology of this rare esophageal neoplasm simulates that of oat cell carcinoma. Four similar cases have been previously reported. The finding of epidermoid differentiation in two of these tumors, including the present one, raises considerable doubt that any are truly oat cell carcinomas of the esophagus. Although it is theoretically possible that an oat cell carcinoma may arise in the esophagus, there is as yet no conclusive evidence for the existence of such an entity.

Carcinoma of the cervix with cylindromatous features believed to arise in mesonerphric duct.

A detailed description of the clinical and morphological aspects of a case of carcinoma of the cervix arising from mesonephric duct remnants is presented, and the literature pertaining to these rare tumors is discussed. At the time of initial surgical treatment the tumor was confined to the cervix; however, eventual metastatic dissemination to the bony and soft tissues of the pelvis, the lungs, and the lower vertebral column resulted in the patient's death 8 years later. The tumor appeared refractory to further attempts at treatment with radiation, progestational therapy, and variety of chemotherapeutic agents. The observation of a focal cylindromatous growth pattern, not previously described in tumors of this type, is presented.

Metastatic malignancy in the submandibular gland.

Metastatic disease in the major salivary glands has been observed and reported in the literature. Often the site of origin of the primary tumor is the skin or mucosal lining of the head and neck structures, and the primary tumors most commonly are melanomas or squamous-cell carcinomas. The most frequently involved salivary gland is the parotid. The submandibular and sublingual glands are rarely involved by mestastatic disease. Secondary lesions arising from distant primary tumors may occasionally involve the parotid gland, but they are extremely rare in the other major salivary glands. The second reported case of metastatic carcinoma in the submandibular gland is presented here. Our case and the previously reported case are similar in that both primary tumors originated in the breast. The clinical and morphologic features are reviewed.

Calcifying epithelial odontogenic tumor. A histologic, histochemical, fluorescent, and ultrastructural study.

A previously unreported calcifying epithelial odontogenic tumor (CEOT; Pindborg tumor) occurring in a Negro patient is presented. Only 12 per cent of these neoplasms have been found in nonwhite patients. Ultrastructural and histochemical studies indicated that the amorphous, acellular, eosinophilic substance present within the tumor was not amyloid. The presence of only sparse calcifications is an unusual histologic variant. No relationship between neoplasm and reduced enamel epithelium could be demonstrated.

Leiomyoblastoma of the stomach. Report of 9 cases.

Gastric leiomyoblastoma is a rare intramural tumor which originates in the smooth muscle. Nine cases were studied with respect to their clinical, radiological, and pathological features. Six distinct radiological patterns may be seen, of which 5 are represented in this series. Most such lesions occur in the gastric antrum. Leiomyoblastomas are generally benign and do not recur following removal.

Endocrine-type granules in cells of glomus tumor of the stomach.

The ultrastructure of a gastric glomus tumor was studied. The tumor cells were found to possess structural features similar to those of smooth muscle cells. In addition, hitherto undescribed granules of endocrine type and cilia were identified.
