Background Ovarian tumor is commonest cancer in female in India. About 80% is benign and 20% of these tumors are malignant. Due to its complex nature, vagueness and non-specificity of the symptoms it produces, the ovarian neoplasm can mislead both the doctor and patients. Hence this study was undertaken with aims & objectives to study the morphology of ovarian specimens as well as estimate serum CA125 as screening tool. Material and Methods: A study of over one year comprised of 75 specimens of ovary diagnosed in the Department of Pathology, Darbhanga Medical College and Hospital, Laheriasarai, Bihar. After thorough gross examination and preparation of H&E stained slides the lesion of ovary were classified as per WHO classification. Also, preoperative blood samples were obtained from patients for estimation of serum CA125 level. Blood samples was also drawn from 20 healthy females in reproductive age group who acted as controls. Results: Of the 75 cases of ovarian mass, based on histology 75% were benign, and 25% were malignant. Surface epithelial tumors were the commonest (68%) of all ovarian tumor, followed by germ cell tumors (13%), sex cord–stromal tumors (6%). Serous Cystadenoma (29%) was the commonest benign tumor and serous cystadenocarcinoma (9%) commonest malignant neoplasm. CA125 levels was raised in epithelial ovarian cancers. Maximum rise was seen in serous cystadenocarcinoma. Exceptionally a small percentage of epithelial cancer showed normal level (false negative). Also, few benign tumors, non-epithelial tumors and even non-neoplastic lesions showed false positive rise in CA125 (false positive). Conclusion: Accurate histopathological evaluation of ovarian specimen is necessary both in terms of therapeutic intervention as well as prognosis. CA125 is an important screening tool for detection of epithelial ovarian cancers.

Objective: To determine the clinico-pathological and histological features of Chondroblastoma (CB). Place of study : Department of Pathology associated with Orthopaedics Department, Darbhanga Medical College and Hospital, Laheriasarai, Bihar. Methodology: The histological slides of all reported cases of CB were retrieved and reviewed for morphological features. Clinical features were noted from surgical pathology reports. Frequency of features was noted. Results: Sixty one cases of CB were identified. Pain was the most common presenting symptom. The age ranged from 10 to 38 years (mean 20 ± 1.98 years; M: F 2.5:1) with 61% patients in the second decade of life. Forty six cases occurred in long tubular bones; distal femur being most common site. Metaphysis, clavicle, temporal bone and metacarpal were also involved. Histologically, all CBs were composed of round to polygonal cells and scattered osteoclast-type multinucleated giant cells and majority had hemosiderin pigment. Chicken-wire calcifications and coarse calcifications were seen in 85% and 26% of cases respectively. A spindle cell component was seen in 54% of cases. ABC-like areas were seen in 10 cases. Mitosis ranged from 1 to 6/10 HPFs. Recurrence was seen in 2 cases. Recurrent tumor showed similar morphology when compared with the initial tumor. Conclusion: CB is a benign tumor but has potential for recurrence. Males are more affected, second decade is more common and distal femur is most common site. Metaphysis, clavicle, temporal bone and metacarpal were the rare sites of CB. Histological features predictive of recurrence were not separately identified.

Background:Tumours and tumour like lesions of the colon and rectum have overlapping clinical presentation and may be difcult to diagnose on clinical grounds alone. Histopathological examination although helpful to arrive at correct diagnosis, at times may be difcult and may require ancillary tests such as immunohistochemistry. Materials and Methods: A prospective cross sectional study enrolled 125 cases of colorectal biopsies after histopathological conrmation of tumours and tumour like lesions. The specimens were received at the Department of Pathology, DMCH, Laheriasarai, Bihar from December 2019 to November 2020. Results: Out of 125 cases, 32 cases were benign tumours, 36 cases were malignant tumours and 57 cases were tumour like lesions. Most common age range was 51-60 years with mean age of 38 years. Males comprised 76.74% and females 23.26% with ratio of 3:1. Juvenile polyp was the commonest lesion. Among benign tumours, tubular adenoma was the most common (19.2%), adenocarcinoma was most common malignant tumour (25.6%) and juvenile polyp was the most common tumour like lesion (27.2%). Left side was most common side (66.67%) and rectum was the most common site (48.8%). Conclusions: The commonest indications for colorectal biopsies were tumours and tumour like lesions. Juvenile polyp was the most common tumour like lesion, tubular adenoma was the most common benign tumour and adenocarcinoma was the most common malignant tumour. Histopathological examination is a gold standard for conrmation of all tumour and tumours like lesions of colon and rectum.

Identification is recognition of an individual by means of various physical features and biological parameters, which are unique to each individual. There are various established parameters for identification of an individual. These are external features (such as birth marks, scar, tattoo marks , occupational marks, malformations), personal features (such as clothes, speech, habits, intelligence, handwriting), assessment of age and sex, determination of race and stature, anthropometric measurements, finger prints, foot prints, lip prints, DNA finger printing and DNA profile, etc. Question of identification arises in every medico legal case be it civil or criminal. The determination of sex is a major criterion for the identification of an individual. It segregates lot of cases for easy and quick identification in a given sample. Age estimation is an integral part of the biological profile in achieving an identification of unknown deceased individual.
