ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP) is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC) of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV). The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.

Cysticercosis is a systemic parasitic disease caused by the larval form of cestodeT. solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The patient most commonly presents with subcutaneous and muscle involvement in the form of nodular lesions. The other most commonly involved sites include eye, brain, bladder wall, and heart. Cysticercosis can be diagnosed on serology, and radiologically but confirmatory diagnosis is based on histopathological examination of the involved tissue biopsy specimen. Fine needle aspiration cytology is a useful low-cost outpatient procedure tool for preoperative diagnosis of cysticercosis and is absolutely essential for diagnosis of the parasitic lesions in a peripheral hospital, one like ours.

Pilomatrixoma (PMX) (pilomatricoma, calcifying epithelioma of Malherbe) is a benign tumor with differentiation toward the hair matrix cells and is common in head and neck region. It is most commonly seen in the first two decades of life and presents as a subcutaneous, small, asymptomatic firm solitary nodule. Fine-needle aspiration cytology (FNAC) has been described as an important preoperative diagnostic investigation though on cytology the diagnosis of PMX is sometimes difficult and misdiagnosed. We describe two patients with gradually increasing asymptomatic swelling on pinna and middle finger. FNAC was done and a diagnosis of PMX was given, further confirmed by histopathological examination. The present cases highlight the importance of FNAC in considering PMX as differential diagnosis of dermal or subcutaneous nodules in locations other than head and neck. Cytopathologists who play an important role in the preliminary diagnosis should keep in mind the variability of the cellular composition of these types of lesions to avoid misdiagnosis.

<p class="abstract"><strong>Background:</strong> The majority (90%) of thyroid lesions are benign as malignancy occurs only 1 in 10 thyroid nodules. The purpose of ultrasonography (USG) and fine needle aspiration cytology (FNAC) is to pick the patients having malignancy for surgical intervention. The objective of present study is to correlate ultrasonography findings with FNAC for diagnosis of malignancy in thyroid lesions by relating these findings to histopathological examination (HPE) reports.</p><p class="abstract"><strong>Methods:</strong> A prospective clinical study carried out from September 2019 to February 2021, in the Department of Ear Nose and Throat (ENT), Mamata Medical College, Khammam, in patients with clinical evidence of thyroid swelling. Ultrasound and FNAC were done in all cases and HPE were done in cases where surgeries were performed at our institution. The results were analysed.  </p><p class="abstract"><strong>Results:</strong> According to USG,<strong> </strong>out of 100 cases 93 cases were found to be of benign thyroid swellings, 4 cases were suspected malignant and 3 cases were found malignant. According to FNAC, out of 100 cases 97 cases were benign and 3 cases were confirmed to be malignant. Two cases which were found to be malignant on both USG and FNAC were confirmed as malignant according to HPE report.</p><p class="abstract"><strong>Conclusions:</strong> USG is a sensitive modality in the assessment of thyroid swellings with good accuracy. FNAC also provides the most direct and specific information about thyroid lesions. It is suggested that USG followed by FNAC provides better diagnosis in thyroid lesions.</p>

<p class="abstract">Malignant oncocytoma is an extremely rare neoplasm of the salivary gland accounting for 0.5% of epithelial salivary gland malignancies and 0.18% of epithelial salivary gland tumors. We report a case of malignant oncocytoma of left parotid gland in a 61-year old female patient. Patient presented with a 6-year history of painless swelling in the left parotid region. Fine needle aspiration cytology of the swelling was suggestive of pleomorphic adenoma. A computed tomography scan performed did not reveal any features suggestive of malignancy. Patient underwent left superficial parotidectomy. However, histopathological examination of the specimen turned out to be malignant oncocytoma. Malignant oncocytoma of salivary glands have rare incidence and may have similar morphologic features with other neoplasms. Despite the tumor being large and malignant in this case, there was no facial palsy preoperatively. As histopathology is often diagnostic, the possibility of malignancy always must be kept in mind preoperatively even when there is no facial palsy or fine needle aspiration cytology not showing up malignancy.</p>
