Cytological diagnosis of microfilariae in clinically unsuspected cases: A retrospective review of 12 cases.

BACKGROUND: Filariasis is a major health problem in India. Despite the high prevalence, microfilariae are rarely found in cytology smears. Most of the cases are incidentally found, solely or in association with other pathologies. AIMS AND OBJECTIVES: This study was undertaken to analyse the prevalence and cytological findings of cases of incidentally found microfilariae in cytology smears (fine needle aspiration cytology [FNAC]/exfoliative cytology) from different parts of the body. MATERIALS AND METHODS: This was a retrospective study over 3 years, in which cases of microfilariae in aspirates from swelling of different locations, body fluids, and pap smears were reviewed, and the clinicopathological data analysed. RESULTS AND ANALYSIS: Out of 11 530 cases of FNAC, 8700 cases of fluid cytology, and 9000 of conventional cervicovaginal smears, 12 cases (0.04%) of incidental findings of microfilariae were documented in cytology smears. The cases were diagnosed from lymph node (one case), hand (one case), scrotal area (one case), axilla (one case), breast (one case), subcutaneous tissue (three cases), urine (three cases), and Pap smear (one case). We found eosinophilia in one case (8.3%) of filarial lesions. We found two cases of incidental findings of microfilariae in association with malignant lesions. CONCLUSION: Cytology smear examination can play an important role in diagnosing occult filariasis in clinically unsuspected cases in association with other pathologies.

Cytomorphological spectrum of cysticercosis: A study of 26 cases.

BACKGROUND: Cysticercosis is a systemic parasitic disease caused by the larval stage of Taenia solium. It is the most common parasitic disease worldwide. Fine needle aspiration cytology can play an important role in prompt recognition of this disease. OBJECTIVE: To study the role of FNAC in the diagnosis of cysticercosis. MATERIALS AND METHODS: This study included 26 patients with parasitic infestation who presented with palpable subcutaneous and intramuscular nodules at different sites. Their clinical presentations and fine needle aspiration cytomorphological features are reported. RESULTS: The age range of these patients was 7-60 years. The majority were males. The most commonly affected site was head and neck followed by upper extremity. Most of the cases were clinically misdiagnosed as lipomas, neurofibromas, lymphadenitis, epidermal inclusion cyst, sialadenitis, and soft tissue tumours. The aspirate was clear fluid in the majority of cases. All of the cases revealed fragments of bladder wall with associated granulomas in seven cases and giant cells in four cases. However, none of the case revealed hooklets. CONCLUSION: Fine needle aspiration cytology can provide a simple, minimally invasive, low-cost, outpatient diagnostic technique for the diagnosis of cysticercosis, as cytological diagnosis is quite clear when the actual parasitic structures are identified in the smear.

Adrenocortical Carcinoma in a 6-Month-Old Infant.

Adrenocortical carcinoma (ACC) is a rare malignant tumor arising from the adrenal cortex and it is even rarer in infancy. These tumors are usually hormonally active. We report a case of ACC in a 6-month-old infant who was brought by her mother with complaints of hirsutism and abnormally looking genitalia. Serum 17-alpha-hydroxyprogesterone and serum cortisol levels were raised. Subsequently, imaging studies revealed a large well-circumscribed soft-tissue mass in the right suprarenal region. The tumor was excised, and on histopathology in conjunction with immunohistochemistry, a diagnosis of ACC was given. Only four other cases of ACC have been reported till date in the literature, with an age of 6 months or younger. Hereby, we present a case of ACC in a young infant.

Angiolipoleiomyoma of the Uterus with a Dermoid Cyst in the Right Ovary: An Unusual Association.

Angiolipoleiomyoma is a benign mesenchymal mass composed of smooth muscle, mature adipose tissue, and abnormal blood vessels. It is rarely diagnosed in uterine masses and its prevalence among benign uterine lesions is 0.06%. We report the case of a 40-year-old female presenting with a complaint of heavy menstrual bleeding. Computed tomography scan revealed a large uterine mass with the right ovarian cyst. Histopathological examination confirmed the nature of the lesion as a benign angiolipoleiomyoma with a dermoid cyst of the right ovary. This rare association is reported to apprise gynecologists to consider this unusual tumor during the management of uterine masses.

Intestinal mucormycosis in a patient with COVID-19: A case report.

The novel coronavirus disease (COVID-19) has spread to all the continents posing a serious threat to global health. It can present with myriad symptoms and complications including susceptibility to fungal co-infections. We hereby describe a case of mucormycosis in a 17 year old COVID-19 positive female with no known comorbidities presenting with abdominal pain and distention and ultimately developing intestinal perforation. Early identication of the symptoms is essential to make a correct and early diagnosis to prevent complications.

Encapsulated papillary variant of medullary carcinoma of thyroid with extensive cystic change: an extremely rare presentation.

Papillary variant of medullary carcinoma of the thyroid is an unusual subtype with many diagnostic challenges. The authors report a case of papillary variant of thyroid medullary carcinoma in a 37-year-old female, who presented with complaints of pain in the thyroid nodule for the latter two months. Contrast enhanced computed tomography (CECT) neck revealed an enlarged and heterogeneously enhancing left lobe of thyroid. This was followed by hemithyroidectomy for suspicion of colloid goitre. Gross examination of the cut surface of the thyroid parenchyma had a sponge like appearance. On histopathology a diagnosis of encapsulated papillary variant of medullary carcinoma thyroid was made with the help of special stains and immunohistochemistry (IHC).

Myxoid meningioma: A case report of an extremely rare subtype of metaplastic meningioma.

Myxoid meningioma is a rare histological variant of meningiomas grouped into the subtype of metaplastic meningiomas (World Health Organization grade I) characterized by the presence of myxoid areas and meningothelial cells along with unique ultrastructural features that help distinguish it from other meningiomas. Hereby, we report a case of a myxoid meningioma in a 40-year-old female who presented with altered sensorium and loss of consciousness. Imaging studies showed a dura-based solitary mass located in the left frontal lobe. The tumor was excised completely. Histopathology revealed a benign appearing myxoid neoplasm with uniform elongated cells, without any atypia and a very low mitotic activity. Immunohistochemical stains showed positivity for vimentin and epithelial membrane antigen confirming the diagnosis of myxoid meningioma. Only seven cases of myxoid meningioma have been reported till date in the literature and ours is the eighth case.
