Obstructive jaundice secondary to abdominal tuberculosis (TB) is an extremely rare presentation. ... more Obstructive jaundice secondary to abdominal tuberculosis (TB) is an extremely rare presentation. However it should be considered in differential diagnosis of surgical jaundice in patients living in endemic zones who are young or immunocompromised. Every effort should be made for early preoperative tissue diagnosis which is often difficult. Over reliance on indirect radiology or serological evidences put clinician in a difficult situation. High index of suspicion and awareness of this disease entity on part of treating clinician is central to optimal management. Early diagnosis offers easy reliable medical cure in contrast to late diagnosis when surgery in conjunction with medical treatment provides cure. Desirable tissue diagnosis is often difficult to achieve in this location. Large majority of reported cases have been diagnosed either during surgery or post operatively on histopathological report. EUS and guided FNA play a crucial role in such cases –a fact highlighted in this rep...

The presence of multinucleated giant cells on FNAC smears of breast lumps have been described only sporadically in the literature. As this is a common specimen in Cytopathology, knowledge of frequency of this variation can be valuable to cytopathologist who identifies the variation and clinician who is involved with the treatment modalities of different breast pathologies. Material and Methods: The present retrospective as well as prospective study was conducted at the department of Pathology. The smears prepared were both wet and dry fixed and were subsequently stained with May Grunwald Giemsa (MGG) as well as Haematoxylin & Eosin (H& E) stain. The stained smears were observed under microscope by at least two expert cytopathologists. Orell was followed for categorizing different breast lesions and the findings were correlated with histop...

Though histopathology is a gold standard, FNAC may suggest a diagnosis of Chondroid syringoma on the basis of thick mucoid aspirates showing distinct biphasic cell population of epithelial and myoepithelial cells in a fibrillary chondro-myxoid stroma. There are not many reported cases of Chondroid syringoma diagnosed cytologically. The present case is of a chondroid syringoma of lower third of right leg, which was primarily diagnosed by FNAC and later confirmed by histology. The present case emphasizes the cytodiagnosis of Chondroid syringoma and its rare location (right leg) for optimal patient management.

The aim and objective of the present study was to evaluate palpable lymph nodes of population working in small to medium scale industries represented as Group A by Fine Needle Aspiration Cytology (FNAC) and to compare the results with the general population designated as Group B comprising dependent non-working family members of Group A population. The results were categorized into two main headings of benign and malignant diseases with sub categorization. The prevalence of benign diagnoses in Group A and Group B was 81% and 79% respectively while that of malignant diagnoses in Group A & Group B was 19% and 21% respectively. The predominant cause of lymphadenopathy in Group A & Group B was reactive lymphadenitis, followed by tubercular lymphadenitis respectively. Metastatic carcinoma was the comment malignant neopl...

We report a case of Osteogenic Sarcoma with chondroid differentiation in a pre-existing Fibrous Dysplasia occurring within one year of surgical resection and without any history of exposure to radiation. To the best of our knowledge and extensive search of literature, malignant transformation of Fibrous Dysplasia in such a short period of time, and without history of radiation exposure has never been reported from India.Journal of Pathology of Nepal (2012) Vol. 2, 335-337DOI: http://dx.doi.org/10.3126/jpn.v2i4.6891

However, association of apocrine metaplasia in papilloma with Ductal Carcinoma in Situ (DCIS) is not very well defined. The lesions with apocrine metaplasia are not only difficult to categories, but also there is controversy regarding their relative risk of subsequent carcinoma development. A case of extensive apocrine differentiation in duct papilloma with DCIS developing in the background of papillomatosis, posing a diagnostic dilemma for the pathologist and a therapeutic challenge for the surgeon, is hereby reported for its uniqueness and rarity. Awareness of this association should be kept in mind by both the pathologist as well as clinician for optimal therapeutic intervention.

Until the pathology underlying atypical uterine bleeding is accurately diagnosed, proper therapy is hardly possible. The objectives of the study were to determine the types and frequencies of pathologies in endometrial curettings of abnormal uterine bleeding & compare different endometrial pathologies in different types of abnormal uterine bleeding in peri and postmenopausal patients. Methods: This is a retrospective study, conducted in the Department of Pathology, in a tertiary care teaching hospital, Kolkata from November 2014 to October 2015. All cases of AUB in the peri and postmenopausal patients with a probable endometrial cause were included in the study. Results: A total of 156 cases were analyzed. AUB was most prevalent in the perimenopausal age group. The most common presenting complaint was menorrhagia (43%). Histopathological diagnosis was not possible in 5 cases with inadequate sample material. Non-organic causes of the endometrium comprised 80.1% of total while in the rest (19.9%) definite organic pathology was found. Among the non-organic causes secretory endometrium(42.9%) and in the organic group polyp(43.3%) was found to be commonest. Malignancy comprises 23.3% and hyperplasia constitutes 30% of total organic causes. Conclusion: Histopathological diagnosis of hyperplasia and malignancy is maximum in the patients presented with menometrorrhagia followed by postmenopausal bleeding. Hereby Histopathological evaluation of endometrial samples is especially indicated in peri and postmenopausal women to rule out neoplastic and preneoplastic conditions.

Clinical presentation of this disorder can be confused with comedogenic acne, keratosis pilaris, eruptive vellus hair cysts, and Favre-Racouchot syndrome. A case of a nonpruritic variant of TS in a 16-year-old boy is reported because of its unusual location as well as presentation in the lower eyelid, giving an appearance of a double eyelid. Although TS is common, it is mostly under diagnosed and henceforth underreported hair follicular disorder. The differential diagnosis of this disorder should be always kept in mind even if it presents in unusual location to avoid unnecessary application of various therapeutic modalities.

Distant metastasis, usually to lungs, bone, and liver is seen much less frequently, with an overall incidence of 6.5–7.3%. A case of 55-year-old male with the previous history of surgery and radiotherapy treated squamous cell carcinoma of the larynx, presenting with a chief complaint of pain abdomen is hereby reported for its unusual diagnosis of metastatic deposits of squamous cell carcinoma in the omentum. Though there are reference available for peritoneum as the distant metastatic site for hypopharyngeal carcinoma, reference for laryngeal carcinoma metastasizing to omentum were not found even with an extensive search of literature. Awareness of unusual sites of distant metastasis such as omentum must be kept in mind for treated laryngeal carcinoma patients presenting with non-specific symptoms like pain abdomen. And also, chances of involvement of unusual site of the distant metastasis increases with advanced tumor-node-metastasis stage and nodal status.

The aim and objectives of this study was to describe the various histopathological fi ndings of fallopian tubes. Materials and Methods: Two thousand fi ve hundred and seventy fi ve cases where fallopian tubes were removed either separately or along with other female genital tract organs were studied retrospectively and their histopathological fi ndings documented. Results: Ectopic pregnancy comprised maximum number of cases closely followed by salpingitis. Primary neoplastic lesions were rare as compared to secondary malignancies. Serial sections of fallopian tube and sections from representative areas are essential for a pathologist so that the diagnosis of these pathological entities is not missed. Conclusion: Though the fallopian tubes remain unremarkable in majority of the surgical pathological specimens,...

Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.
