Introduction: Salivary gland swellings can occur because of inflammation, cyst or neoplastic process. Neoplasms of salivary glands are relatively rare comprising less than 2% of all human tumors. Prevalence of salivary of gland lesions differ from place to place. There are more than 30 morphologically different types of salivary gland neoplasms; ma...

Background: To study and compare cytomorphological features of histologically proven cases of benign phyllodes and cellular fibroadenoma.Methods: Smears of histologically-proven cases of benign phyllodes and cellular fibroadenoma in one year, were reviewed. The cellular fibroadenoma had epithelial and/or stromal hypercellularity. The stromal and ep...

Introduction: Atherosclerosis accounts for a large proportion of cardiovascular system associated morbidity and mortality. Coronary artery disease (CAD) is the leading cause of global deaths with about 80% of burden occurring in developing countries. Material & Methods: In order to assess the magnitude of the problem, a retrospective study of autop...

A choriostoma is an aggregate of microscopically normal cells or tissues which occurs in an aberrant location. It follows a benign course, rarely seen in head and neck region. A choriostoma of the palatine tonsil is very rare; less than 10 cases were reported till date. A 11-year-old male referred to ENT OPD with chronic tonsillitis and underwent t...

Background and Objective The currentstudy aimed at investigating the histomorphological spectrum of cervical intraepithelial and invasive lesions assessing the diagnostic significance of P16/INK4a and Ki-67 in such lesions, andcorrelatingP16/ INK4a and Ki-67 immunoexpression with histologic type and grade. Methods A total of 60 cases were selected...

Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6%...

Malignant fibrous histiocytoma (MFH) usually presents in the extremities or retroperitoneum. MFH arising from renal parenchyma or renal capsule is extremely rare, only few cases have been reported in literature and portend a poor prognosis. Renal MFH is differentiated from renal cell carcinoma, renal sarcoma, and sarcomatoid renal tumor only by his...

Isolated tuberculous epididymo-orchitis is rare and may present with clinical and radiological features similar to those of testicular tumor. It is thus a diagnostic and therapeutic challenge. A 40 yrs old male presented with left sided mass in scrotum for past 6 months, which was clinically and radiologically diagnosed as testicular tumor with hyd...

Trichoadenoma is a rare benign, slowly growing, cutaneous tumour of the hair follicle first described by Nikolowski in 1958. It presents as a non-specific nodule over the face or buttocks. However, unusual sites such as the neck, upper arm, thigh, shoulder, and shaft of the penis may also be affected. The tumour is less mature than a trichofollicul...

Malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. These tumors are rapidly growing and can metastasize. We report a case of 13-yr-old girl who presented at SHKM GMC, Nalhar, Mewat, Haryana, India in December 2013 with huge abdominal lump of a malignant mixed...

Sternocleidomastoid tumor, also known as fibromatosis colli, is a rare form of fibromatosis in infants which is a rare, benign, and self-limiting tumor of infancy presenting as a well-circumscribed, hard, immobile, and fusiform swelling in the lower or middle portion of the sternocleidomastoid muscle. Birth injury associated with difficult labor is...

Trichoepithelioma is a benign tumor of follicular origin that presents as small, skin-colored papules predominantly on the face. When more than one family member is affected, the disease is known as multiple familial trichoepithelioma (MFT). It is a rare autosomal dominant skin disease. Malignant transformation is very rare. We describe here a case...

Cerebral aspergillosis is a rare pathology with fatal outcome. It is mostly a post-mortem diagnosis because the initial symptoms are mostly nonspecific and the existing diagnostic modalities are not sensitive to ensure early and definite diagnosis. The clinical manifestations and disease severity are dictated by the immunologic state of the patient...

Low-grade adenosquamous (LGAS) carcinoma is rare morphological variant of metaplastic breast carcinoma. Only few cases have been reported in the literature so far. We reported a case of LGAS carcinoma in 55-years-old female who presented with huge lump breast since 6 months. On fine needle aspiration cytology, it was diagnosed as mesenchymal tumor...

Paraganglioma of the urinary bladder is a rare tumor accounting for ˂0.06% of all bladder tumors and ˂1% of all pheochromocytomas. The distinction of paragangliomas from urothelial carcinoma is likely to be critical because of differences in therapeutic management. We report a case of 24-year-old female who presented with a complaint of intermitten...

Worldwide, ovarian carcinoma continues to be responsible for more deaths than all other gynecologic malignancies. It usually occurs in older women and the average age at presentation is 50 years. Brenner tumor of the ovary is very rare, mostly benign, small, and unilateral. Malignant Brenner tumor is much rarer. These tumors are believed to arise f...

Metaplastic Breast Carcinoma (MBC) is very rare, and metaplastic carcinoma with osseous differentiation is even rarer. Here we report a case of metaplastic breast carcinoma with extensive osseous differentiation. A 65 year’s female presented with the complaint of lump left breast for the last 6 months. Fine Needle Aspiration Cytology (FNAC) suggest...

Giant cell tumor (GCT) of bone involving small bones of hand and feet is a rare entity. But in foot and hand it is more aggressive and recurrence rate is high as compared to long bones. We report a rare case of GCT of talus that was managed on the lines of tuberculosis by an orthopaedic surgeon for six months. Core biopsy of the lesion revealed mul...

Myoepitheliomas are rare benign salivary gland neoplasms which originate from ectodermally derived contractile smooth muscle cells i.e. myoepithelial cells which lack ductal differentiation. They account for only 1-1.5% of all salivary gland neoplasms. Myoepithelioma was considered as a variant of Pleomorphic adenoma in the past, but since 1991 it...

Primary thyroid gland lymphomas (PTLs) typically occur in middle-to older-aged individuals in the setting of lymphocytic thyroiditis with a predilection for females. Diffuse large B-cell lymphoma is the most frequent histologic subtype of thyroid lymphomas. Small lymphocytic lymphoma (SLL) belongs to the least common subtypes of thyroid lymphoma. I...

Prostatic carcinoma is a common and growing public health problem. Histological evaluation is fairly adequate for assessing tumor differentiation, but tumor proliferative activity is difficult to measure. Increasing evidence suggests that the factors controlling cell cycle progression also modulate the rate of ribosome biogenesis. Despite the influ...

Small bowel lymphoma is a comparatively rare disease. Usually neither typical nor explicit symptoms are determined during its course and the first manifestation can be noticed when a complication occurs. Burkitt's lymphoma is a high-grade, aggressive and rapidly growing B-cell neoplasm, which has low long-term survival rates. Sporadic Burkitt's lym...

Abstract Hydatid disease, a zoonosis, occurs worldwide but its prevalence is high in those countries where sheep and cattle raising constitute an important industry due to close association between man, sheep and dog. Most common sites of involvement by hydatid disease are liver followed by lung. Splenic involvement by hydatid disease is very rare...

Sebaceous carcinoma is a rare, highly malignant, and potentially lethal tumor of the skin, which most commonly occurs in the eyelid. The neoplasm arises from sebaceous glands, such as those of the eyebrow. It represents 1-5.5% of eyelid malignancies and is considered to be the third most common eyelid malignancy after basal cell carcinoma and squam...

Sialoblastoma is a rare congenital tumor of salivary gland. Herein, we report a case in a 5-year-old child who presented with a painless swelling in parotid region since birth and also review the literature. Surgical excision of parotid gland was done. Further, histopathological and immunohistochemical examination was performed and a final diagnosi...
