Endometrial squamous cell carcinoma is an extremely rare female genital malignancy. Only 26 cases which fulfil the Fluhmann criteria have been reported in the literature. In this report, 2 cases of endometrial squamous cell carcinoma are presented, with a review of related current knowledge.

The obstetrician is rarely confronted with a pregnant patient who presents with a large suspicious pelvic mass. Diagnostic tools are not always of value and laparotomy may be performed for obstetric and histopathologic reasons. In this article we present an interesting case of an unusual pelvic mass in pregnancy secondary to benign lymphoepithelial disease (Castleman's disease). We could not find a case similar to the one reported in the medical literature.
A preoperative presumptive diagnosis of ameloblastoma is sometimes made in the light of available clinical and radiological data, which are generally not very characteristic. The final diagnosis can only be made on the basis of histologic features. In this paper, a case of ameloblastoma diagnosed preoperatively by fine-needle aspiration cytology is presented and the potential value of this technique for diagnosing oral lesions is discussed.
Spontaneous kidney rupture as the initial manifestation of polyarteritis nodosa is rare. We present 4 such patients who underwent nephrectomy. We suggest primary nephrectomy in patients with spontaneous kidney rupture and resultant retroperitoneal hematoma in whom no preoperative diagnosis is available.
Carcinoid tumor of the testis is rare and its histogenesis is controversial. We report a case of carcinoid tumor in an undescended testis with electron microscopic evidence of neurosecretory granules.

Primary squamous cell carcinoma (SCC) of the stomach is a very rare tumour. We report a case of SCC of the stomach in a 56-year old woman who had metastases to the liver and abdominal lymph nodes.
Aspiration cytologic findings in a case of benign lymphoepithelial lesion (BLL) of the parotid gland are presented. The aspirate contained a polymorphous lymphoid population, histiocytes, myoepithelial and ductal epithelial cells and numerous bluish, calcified bodies. A cytologic diagnosis of benign nonneoplastic lesion, consistent with chronic sialadenitis and microlithiasis, was made. The clinical impression of neoplasia was inconsistent with the cytologic findings. Subsequent histologic examination showed classic BLL with microcalcifications as an unexpected feature. The value and limitations of fine needle aspiration cytology in the diagnosis of nonneoplastic salivary gland lesions and the differential diagnosis of BLL are discussed.
A case of cementifying fibroma in the right lateral mandible was diagnosed by fine needle aspiration (FNA) cytology. The aspirate was a cellular specimen composed of clusters of oval and spindle-shaped fibroblasts with no atypical features. These cells were admixed with spherical, calcified structures. A diagnosis of "consistent with benign fibroosseous lesion, suggestive of cementoossifying fibroma" was made, and subsequent histologic examination confirmed this cytologic diagnosis. The clinical, cytologic and histologic findings in the case are presented, and the value of FNA cytology in the diagnosis of jaw lesions is discussed.
Fine needle aspiration cytologic findings in two cases of malignant lymphoepithelial lesion (MLEL) of the parotid glands are presented. Aspirates of both cases showed individual or cohesive clusters of tumor cells intermingling with mature lymphocytes. Cervical lymph node aspirates in both cases were similar to those seen in the parotids. Our findings suggest that neither cytology nor histology of the cervical lymph nodes is conclusive in establishing the primary site of a metastatic lymphoepitheliomalike carcinoma. MLEL of the salivary glands must be included in the differential diagnosis.
Fine needle aspiration cytology of oral cavity and jaw bone lesions was performed on 102 patients. The cytologic diagnoses were compared with the results of histologic examination. Thirteen of the 15 histologically malignant lesions and 71 of the 87 histologically benign lesions were cytologically diagnosed accurately. In 12 (92%) of the malignant and 69 (97%) of the benign lesions, specific cytologic diagnoses were given that proved the same or very similar to the final histologic diagnoses. This study showed that the overall accuracy of fine needle aspiration cytology in the oral cavity and jaw bones is high and is not significantly different from that obtained in other body regions.
