The spectrum of cytological findings in patients with BCG lymphadenitis: A series of 13 cases.

Context: Bacillus Calmette-Guérin (BCG) vaccine has been used to prevent tuberculosis and/or its severe complications for long. BCG lymphadenitis is a common complication of the vaccine, which is sometimes subjected to cytological examination. The aim of the study is to describe the cytological findings of BCG lymphadenitis.

Diffuse Leptomeningeal Glioneuronal Tumor: A Rare Case Report with Review of Literature.

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare tumor that was defined as a separate entity in the 2016 World Health Organization classification of brain tumors. It is most common in the pediatric age group. The diagnosis of this tumor can be made preoperatively by its characteristic imaging findings of diffuse intracranial and intraspinal nodular leptomeningeal thickening and enhancement associated with small cyst-like nonenhancing lesions in the brain and spinal cord.

Coexistent dysembryoplastic neuroepithelial tumour and pilocytic astrocytoma.

Dysembryoplastic neuroepithelial tumour (DNET) is an uncommon mixed glioneuronal tumour. DNET is classified as Grade I neoplasm in revised World Health Organization classification of tumors of the nervous system. DNET is commonly seen in the temporal lobe of children and young adults with features of pharmacoresistant complex partial seizures.

Intraoperative Squash Cytologic Features of Subependymal Giant Cell Astrocytoma.

Subependymal giant cell astrocytoma (SEGA) is a low grade (WHO Grade I) tumor, usually seen in patients with tuberous sclerosis complex and commonly occurs at a lateral ventricular location. Intraoperative squash cytologic features can help in differentiating SEGA from gemistocytic astrocytoma (GA), giant cell glioblastoma and ependymoma, in proper clinical context and radiological findings, which may alter the surgical management. Here, we present a case of SEGA with squash cytologic findings and a review of cytology findings of SEGA presently available in the literature.

Fibroma of the tendon sheath: A diagnostic dilemma on fine-needle aspiration cytology.

Fibroma of the tendon sheath (FTS) is an uncommon benign soft tissue tumor (STS) of the tendon sheath. Clinical and radiological features are not distinctive enough to clinch the diagnosis preoperatively. Although histological features are well described, diagnostic cytological features of FTS are still lacking.

Primary Cutaneous CD8(+) CD30(+) Anaplastic Large Cell Lymphoma: An Unusual Case with a High Ki-67 index-A Short Review.

Primary cutaneous anaplastic large cell lymphoma (PCALCL) is a part of the spectrum of CD30(+) cutaneous lymphoproliferative disorder, characterized by variable degrees of CD2, CD3, CD4 and CD5 expression by lymphoid cells. PCALCLs with an expression of cytotoxic phenotype (CD8(+)) and cytotoxic proteins are uncommon. Cutaneous CD8(+) CD30(+) lymphoproliferative lesions are difficult to classify, diagnose and may be the cause of misdiagnose.

Intradural spinal granular cell tumor.

Granular cell tumor is a rare, usually benign tumor with classical histomorphology. Location of tumor varies widely within body, but spine is distinctly a rare location for this tumor. We report a rare case of granular cell tumor involving intradural extramedullary portion of lumbar region of spinal cord.

Well-differentiated papillary mesothelioma of the peritoneum: a diagnostic dilemma on fine-needle aspiration cytology.

Objectives: Well-differentiated papillary mesothelioma of the peritoneum (WDPMP) is an uncommon subtype of epithelioid mesothelioma. Usually, WDPMP has a benign course, while a few patients have multiple recurrence and malignant transformation on long-term follow-up. The histology of WDPMP has been well studied compared with the cytology.

Anterior mediastinal masses: A study of 50 cases by fine needle aspiration cytology and core needle biopsy as a diagnostic procedure.

Background: Mediastinal tumors are an uncommon abnormalities found in clinical practice. Anterior mediastinum is the common site and tissue diagnoses of anterior mediastinal masses (AMMs) are very important for correct therapeutic decision.

Objective: We evaluate the different malignant AMMs in various age groups and the sensitivity of fine needle aspiration cytology (FNAC) and core needle biopsy (CNB).

Primary intratesticular rhabdomyosarcoma in pediatrics.

Testicular sarcomas constitute only 1-2% of all testicular tumors and are mostly associated with germ cell tumor. Primary intratesticular rhabdomyosarcoma is rare and only 14 cases have been reported in the literature till date. It should be differentiated from germ cell tumor with sarcomatous component, other intratesticular spindle-cell sarcomas and paratesticular rhabdomyosarcoma.

Granular cell tumor of hand presenting as subcutaneous nodule mimicking dermal adnexal tumor: A diagnosis by cytology.

Granular cell tumor (GCT) is an uncommon tumor and is believed to be of schwannian origin. GCT is benign but rare malignant cases are recorded. GCT occurs in almost any part of the body.

Solid pseudopapillary tumor of pancreas in a male child: a diagnosis by fine needle aspiration cytology.

Solid pseudopapillary tumor (SPT) is an uncommon pancreatic neoplasm with low malignant potential. It occurs predominantly in young women. It is very rare in males and nonrelated pediatrics.

Recurrent low-grade astroblastoma with signet ring-like cells and high proliferative index.

Astroblastoma is a rare primary glial tumor of children and young adults. Radiologically astroblastoma presents as a large well-circumscribed supratentorial, solid-cystic heterogeneous mass. Histology shows perivascular pseudorosettes with hyalinization.
