Calcifying fibrous tumour: a rare case report of an exceptional lesion localized in retroperitoneum, mesentery and pelvis

Calcifying fibrous tumours are rare benign lesions affecting mostly children and young adults. A 17-year-old female presented with abdominal pain and abdominal distention. Physical examination revealed intra-abdominal mass occupying retro peritoneum and right iliac fossa. Excisional biopsy from peritoneum and mesentery were performed. Histopathologically, it was composed of hypocellular hyalinised collagenized stroma, spindle cells, psammomatous and dystrophic calcification and mononuclear inflammatory cell infiltration. Authors are here in reporting a case of calcifying fibrous tumour and discussing its clinical and morphological features with regard to the literature.

Plasmablastic lymphoma of transverse colon: a rare case report

Plasmablastic lymphoma (PBL) is a rare aggressive subtype of non-Hodgkin's lymphoma with large neoplastic cells. It is usually associated with human immunodeficiency virus (HIV) infection but also identified in patients with solid organ transplantation and in immunocompetent patients. It frequently presents as a mass in oral cavity, but has also been described in other extra-oral sites like gastrointestinal track, skin, genitourinary track, nasal cavity, paranasal sinuses, etc. It is characterized by plasmablastic features and an immunoprofile close to plasma cells, Epstein–Barr virus (EBV) positivity and MYC gene dysregulation. We report a case of a 40 year old HIV positive male who presented with intestinal obstruction having mass in transverse colon. Histopathological examination of the excised mass revealed submucosa and muscularis propria infiltrated by monotonous population of medium to large sized lymphoid cells with plasmacytic differentiation. The tumour cells were immunoreactive for EMA, CD138 and Vimentin and immunonegative for LCA, CK, S-100, Chromogranin, CD20, CD30, CD3. Thus the final diagnosis of Non-Hodgkins Lymphoma – Consistent with Plasmablastic Lymphoma was made. PBL should be carefully differentiated from Plasmablastic Plasma cell myeloma, other CD20 negative B-cell neoplasma i.e. primary effusion lymphoma, anaplastic lymphoma Kinase (ALK)-positive large B-cell lymphoma, large B-cell lymphoma arising in human herpesvirus 8 (HHV-8)-associated multicentric Castleman disease.

A study of cervical Papanicolaou smears examination in patients with abnormal vaginal discharge

Background: Reproductive tract infection represents major public health problem in developing countries. Cervical infections are common problems among women of reproductive age and associated with clinical complaints of vaginal discharge. Pap smear is a screening test to diagnose various abnormal pathology of cervix. Aims and objectives of this study was to identify various causes of vaginal discharge and frequency of various pathogenic microorganisms in cervical smear.Methods: This was hospital based descriptive study carried out on 300 female patients who attended obstetrics and gynecology clinic at tertiary care hospital with compliant of vaginal discharge. Cervical smear samples were collected, conventional smears were prepared by trained technical staff and stained using Papanicolaou (Pap) technique.Results: The most common age group affected with vaginal discharge was 26 to 35 years with 115 cases. The most common associated symptom was lower abdominal pain seen in 75 cases. Most frequent findings on per speculum examination was thick whitish discharge in 186 cases and the most common pathogenic organism found was Bacterial Vaginosis (BV) in 177 cases.Conclusions: The study emphasizes the need for educating women of rural community to raise the awareness for cervical Pap screening.
