Basal cell adenocarcinoma of submandibular salivary gland-problems in cytologic diagnosis.

Basal-cell adenoma and basal-cell adenocarcinoma of the salivary gland are rare tumors. Fine-needle aspiration cytology of these tumors, particularly those of basal-cell adenocarcinoma, has rarely been described in the literature. In this report, we describe the clinical, cytomorphologic and histopathologic features of basal cell adenocarcinoma in a 48-year-old male patient. Fine-needle aspiration specimen showed abundant cohesive groups of basaloid cells revealing focal anisonucleosis and nuclear atypia. The tumor cells also showed rosette-like arrangement around central eosinophilic globule. Pertinent literature is reviewed and differential diagnosis are discussed.

Role of AgNORs in thyroid lesions on fine needle aspiration cytology smears

Background: Fine needle aspiration has an important role in diagnosis of thyroid neoplasm. However, it is difficult to differentiate between follicular adenoma and follicular carcinoma by cytology alone. Recently, silver staining has been performed for nucleolar organizer regions (AgNORs) to differentiate various tumors. Aims: The present study was undertaken to see if the AgNOR technique could distinguish between benign and malignant lesions, particularly, follicular neoplasm. Materials and Methods: One hundred forty cases of thyroid lesions were examined, which included colloid goiter (n = 36), multinodular goiter (n = 38), subacute thyroiditis (n = 6), Hashimotos thyroiditis (n = 17), lymphocytic thyroiditis (n = 3), follicular neoplasm (n = 18), Hurthle cell neoplasm (n = 3), papillary carcinoma (n = 16), and medullary carcinoma (n = 3). Diagnosis was confirmed by histopathology in 80 cases. The usual one-step silver colloidal reaction was performed at room temperature for 35 minutes and intranuclear dots of silver deposits were counted in 100 cells. Results: AgNOR counts of benign and malignant lesions were compared and were found to be statistically significant (P Conclusions: AgNOR counting in fine needle aspiration smears is a simple, sensitive, and cost-effective method for differentiating benign from malignant thyroid follicular neoplasms.

Giant cell tumor of soft tissue: Cytological diagnosis of a case.

Giant cell tumors of soft tissue (GCT-STs) are rare neoplasms and are mainly seen in adults and in the elderly population, usually in the extremities. When evaluated along with clinical features, the cytological features are sufficient to distinguish GCT-STs from other more common tumors with giant cell morphology. We report here a case of a giant cell tumor of soft tissue diagnosed on the basis of fine needle aspiration cytology and confirmed after histopathology.

Ancient schwannoma of the neck mimicking soft tissue sarcoma.

early experience with LT for HCC was disappointing, with 5-year survival rates of approximately 25%, outcomes have significantly improved over time, partially due to the application of stringent eligibility criteria when selecting patients for undergoing LT for HCC. Currently, patients undergoing LT for HCC have a 5-year survival rate exceeding 70%, which is similar to the survival seen in patients undergoing LT for other indications. [3] The observed tumor recurrence rates are less than 15% at 5 years. [3,5] It has therefore been suggested that LT is an effective option for patients with HCC corresponding to the Milan criteria, i.e., solitary tumor ,5 cm in size or up to three nodules ,3 cm in size.

Metastatic ovarian tumor.

58-year-old woman with a history of breast carcinoma presented with a bilateral ovarian tumor. On fine needle aspiration cytology, diagnosis of metastatic adenocarcinoma was made. At subsequent hysterectomy and bilateral salpingo-oophrectomy, specimen showed extensive metastatic carcinoma involving both ovaries.

Sclerosing stromal tumor of the ovary: A case report

Sclerosing stromal tumors are benign ovarian neoplasms of the sex cord-stromal category, occurring predominantly in the second and third decades of life. Herein, we report a 23-year-old female who presented with pelvic pain, irregular menses but normal hormonal status and was diagnosed as having a right ovarian tumor. A right oophorectomy was performed, and microscopic examination revealed a sclerosing stromal tumor of the right ovary. We stress the importance of being familiar with sclerosing stromal tumors when evaluating ovarian neoplasms in young women, in order to contribute to the appropriate clinical management, preventing extensive and unnecessary surgery, and preserving fertility.

Hemangioma of rib masquerading a malignancy

Hemangioma of bone is a rare bone tumor accounting for <1% of all osseous tumors. Hemangiomas are common in skull and vertebrae but uncommon in rib. Rib hemangiomas may increase in size over a period and may cause symptoms due to increasing size. Preoperative diagnosis is not always possible due to overlapping radiological features between benign and malignant lesions. Use of preoperative aspiration and biopsy has their own risks and benefit. Excision of rib in case of monostotic rib lesions is the treatment of choice due to low risk of recurrence and no reported postoperative complications. We report a case of rib hemangioma which mimicked a malignancy preoperatively.

Limbal carcinoma: Common malignancy at uncommon site

Limbus is the region of the eye between the cornea on one side and the sclera on the other. Limbus houses the stem cells. Neoplastic growths in limbus are the most common among growths of cornea and conjunctiva owing to the transition nature of the limbus. Although squamous cell carcinoma (SCC) is the most common carcinoma of limbus, its incidence is only 0.2–3.5/100,000. We present a 65-year-old patient with a limbal growth over a long period initially diagnosed as limbal stem cell deficiency. The patient sequentially developed epithelial dysplasia and then SCC. The complete excision of eyeball had to be done due to the recurrent nature of the lesion. The need for early detection of limbal mass and its prompt treatment cannot be overemphasized. Limbal growths have a good prognosis when treated early since they do not invade cornea and conjunctiva readily. Treatment is both surgical and medical. We present this case because of its rarity with a review of literature.

Leiomyoma of scrotum

Leiomyoma is a benign tumor of smooth muscle. Leiomyoma originating from the scrotum is rare. We report here a case of 50-year-old male who presented with a lump in the left side of scrotum. Clinically, it was diagnosed as sebaceous cyst and was excised. The histopathology showed findings consistent with leiomyoma. There was no cytological atypia. The final diagnosis of solitary scrotal leiomyoma was given.

Cyto-histological correlation of sarcomatoid carcinoma of kidney

Sarcomatoid renal cell carcinoma (RCC) is a rare malignancy constituting 0.7% to 13.2% of all renal parenchymal malignancies. It is also called anaplastic carcinoma, spindle cell carcinoma or carcinosarcoma. The sarcomatoid differentiation is not a distinct histological entity, but it confers high aggressiveness on any subtype of RCC. Cytology of sarcomatoid RCC has rarely been described in literature. We describe cytology of a renal tumor that was later proven to be sarcomatoid RCC on histopathology and immunohistochemistry.
