Enterobiasis is one of the most common human parasitic infections. It is considered an intestinal parasite, but cases of extra-intestinal affections exist, notably infections of the female genital tract. Enterobius vermicularis (EV) eggs (or ova) have been found in the cervical smears of two patients in our institute during the last 16 years. No gynaecological or gastrointestinal symptoms were reported, and there was no known intestinal infection in these two cases. A review of the available literature revealed rare cases of vaginal enterobiasis, with a wide range of clinical presentations, many patients being asymptomatic...

Head and neck large cell neuroendocrine carcinoma (LCNEC) is a rare high-grade malignant tumor with neuroendocrine differentiation. We report a case of LCNEC causing difficulty in cytological diagnosis. A 60-year-old man with right-sided face pain presented with a swelling at the right cheek, and he complained of right nasal obstruction and lacrimation. Preoperative fine-needle aspiration cytology (FNAC) showed high cellularity, with a moderate number of clusters of tumor cells on an abundant necrotic background...

Alveolar soft part sarcoma is a very rare, slow growing highly angiogenic tumor with poor prognosis. Most common site in children and infants is head and neck region and in adults it most commonly occurs in extremities especially thigh. In our case study, an 8 years old female patient presented with a gradually progressive left shoulder lump. FNAC from the lesion showed cellular smears with polyhedral and spindly cells showing abundant finely vacuolated cytoplasm, nuclear pleomorphism, intranuclear pseudoinclusions, and few bare nuclei...

Pulmonary blastoma is an uncommon tumour. It constitutes <0.1% of all resected lung cancers. It is even more rare in children with only a few case reports describing this entity in them. Pulmonary blastoma should not be confused with pleuropulmonary blastoma which is a paediatric lung tumour with different morphology and better outcome. Here we take the opportunity of describing pulmonary blastoma in a 3 years old child along with its cytological findings.

BACKGROUND: Diagnosis of metastatic prostate adenocarcinoma (metPA) in cytology specimens can be challenging and frequently requires the use of immunohistochemistry (IHC). Prostate specific membrane antigen (PSMA) and NKX3.1 have emerged as promising IHC markers to determine prostatic origin of metPA in surgical specimens. Our goal is to evaluate the performance of PSMA and NKX3.1 and compare them with those of prostate-specific antigen (PSA) and prostate specific alkaline phosphatase (PSAP) in the cytological diagnosis of metPA MATERIALS: Cytology specimens from patients with a history of prostate adenocarcinoma at our institution between January 01, 2005 and December 31, 2015 were retrieved...

Primary thymic adenocarcinoma is an extremely rare tumor, and thymic enteric type adenocarcinoma has recently been proposed as a distinct pathological entity. Herein, we report the first cytological description of thymic enteric type adenocarcinoma. A 29-year-old Japanese female without a significant past medical history was found to have an abnormal chest shadow. Chest computed tomography demonstrated a well-circumscribed tumor in the anterior mediastinum, and thymectomy was performed. The Papanicolaou staining of the touch smear of the resected tumor demonstrated tightly cohesive epithelial cell clusters in a necrotic background...

Nocardia species and Actinomyces species are 2 of the most commonly diagnosed filamentous bacteria in routine cytopathology practice. These genera share many overlapping cytomorphologic features, including their thin, beaded, branching, Gram-positive, GMS-positive filamentous structures that fragment at their peripheries into bacillary- and coccoid-appearing forms. Features that help distinguish between these 2 microorganisms include the width of their filamentous structures, the angles at which they branch, and their ability or lack thereof to retain a modified acid-fast stain...

Uterine tumor resembling an ovarian sex-cord tumor (UTROSCT) is a rare type of uterine neoplasm. We present an extremely rare case of lung metastases from a UTROSCT focusing on the cytologic features. A 69-year-old Japanese woman was admitted to our hospital for further examination and treatment for abnormal shadows in the right lung field. She had a history of total hysterectomy for UTROSCT. Moreover, she underwent wedge resection of the right middle lobe for lung metastasis of UTROSCT in 2011. Enhanced chest computed tomography scan revealed a solid nodule 8 mm in diameter in the right upper lobe and a well-demarcated 33-mm mass or nodule in the lower lobe...

BACKGROUND: Use of smokeless tobacco (ST) is increasing in many communities. We investigated whether ST alters the cytological and cytomorphometric features of buccal mucosa cells. METHODS: Twenty male participants who had used Nicotiana rustica Linn.-containing ST (Maras powder) for at least 10 years, and 20 healthy male controls who did not use ST, were included in this study. After rinsing the mouth with water, samples were taken using a toothbrush from the buccal mucosa of subjects in both groups...

BACKGROUND: Cysticercosis is a common parasitic infection in many Asian countries. The histopathological features of this parasitic infection are well established, however, the subtle cytological features and their importance in diagnosing this condition need more elaboration. In this case series we have reiterated the role of fine-needle aspiration cytology (FNAC) in the diagnosis of cysticercosis in clinically unsuspected cases, thereby obviating the need for a biopsy. METHODS: Sixteen patients presented with palpable subcutaneous swellings...

Chondroblastoma is a rare, cartilage producing primary neoplasm of the bone. Although generally benign, chondroblastoma is placed in the "intermediate, rarely metastasizing" category in the 2013 World Health Organization classification of bone tumors. It typically involves the epiphysis of long tubular bones and is exceptionally located in the vertebral column. To the best of our knowledge, less than 35 cases of vertebral chondroblastoma have been reported in the literature. We report a case of chondroblastoma involving D6 -D7 vertebrae in a 17-year-old male patient, diagnosed on intraoperative crush cytology and later confirmed on histopathology...

Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease (RDD) is a rare benign disorder that primarily affects the lymph nodes. Localized lymphadenopathy is the most common clinical manifestation of this disorder. However, RDD has been described in several extra-nodal sites including the head and neck region, soft tissue, skin, upper respiratory tract, gastro-intestinal tract and central nervous system (CNS). Involvement of the bone is considered very rare, occurring in less than 10% patients...

BACKGROUND: ALK gene rearrangement is an important class of gene mutations in pulmonary adenocarcinoma. ALK-positive pulmonary adenocarcinoma exhibits characteristic histological features, such as signet ring cell carcinoma (SRCC) and a mucinous cribriform structure. However, when insufficient histological specimens are obtained, ALK-positivity must be predicted based on cytological features. The purpose of this study was to clarify the cytological characteristics of ALK-positive pulmonary adenocarcinoma...

Poorly differentiated primary pulmonary synovial sarcoma (PD-PPSS) is a rare, aggressive neoplasm, which occurs in 0.5% cases of all lung malignancies. The diagnosis of PD-PPSS can be very challenging on cytology samples. We present here an unusual case of PD-PPSS diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), in the setting of known history of diffuse large B-cell lymphoma. Diff-Quik and Papanicolaou stains showed cellular specimen with clusters of highly atypical small round blue cells admixed with lymphoid elements; and some with denuded cytoplasm...

Rafael Martínez-Girón, Liron Pantanowitz
Cerebrospinal fluid cytology examination is a common and reliable primary and/or complementary procedure for the diagnosis of central nervous system (CNS) disorders. This review provides an update of aseptic meningeal disorders that may be encountered in cytopathology practice. The article covers the cytological findings and helpful ancillary studies needed of nonmalignant aseptic CNS disorders such as viral, bacterial, fungal and parasitic infections, and other noninfectious diseases, such as Mollaret´s meningitis (recurrent benign lymphocytic meningitis), Guillain-Barré syndrome, multiple Sclerosis, subarachnoid haemorrhage, and drug-induced disorders...
