Tumours of eyelid: a clinicopathologic study.

A retrospective study of 207 cases of eyelid tumours and tumour like lesions, diagnosed histopathologically, was carried out for the period 1957 to 1991. There was a slight preponderance of males as the male/female ratio was 1.3:1. The age of the cases ranged from one to 80 years. Benign tumours were usually seen in the first two decades whereas the malignant tumours were common in the age group of 40 to 60 years. Malignancy was noticed in 85 cases (41.1%). Of these cases of malignant tumours, basal cell carcinoma was the commonest (38.8%) followed by sebaceous carcinoma (27.1%), squamous cell carcinoma (22.4%), basisquamous cell carcinoma (8.2%) and melanoma (3.5%). The ratio of basal cell carcinoma to squamous cell carcinoma was 1.74: 1. Of the 122 benign lesions common ones were vascular tumours (21.3%), neural tumours (18.0%), dermoid cysts (16.4%), squamous cell papilloma (13.1%) and naevi (12.3%).

Pleomorphic adenoma of skin (chondroid syringoma) involving the eyelid.

Lid tumours are fairly common. However, pleomorphic adenoma (chondroid syringoma) is quite rare. In a series of 207 eyelid tumours and tumour like lesions, pleomorphic adenoma was observed in a male aged 41 years; its incidence being 0.48%.

Incidence of cancer breast at Aligarh.

Breast cancer is a worldwide problem but its frequency varied from place to place. One hundred twenty-four breast cancer cases were reported during the ten years of survey at Aligarh constituting 12.4% of all malignant lesions. Peak incidence was found between the age of 41 and 50 years. More patients were from lower socio-economic group belonging to both Hindu as well as Muslim communities. Nearly 90% of cases had their menarche by the age of 14 years. Male breast cancer was 4%. Right breast was more commonly affected than that of the left. The upper and outer quadrant was involved in more than one-third cases and more than half the lesions occurred in upper half. There were 97.6% of epithelial and 2.4% of stromal tumours. Among epithelial tumours, highest incidence (72.38%) was that of invasive duct carcinoma followed by medullary, colloid and Paget's disease.

Histological changes in reptilean spinal cord transection: correlation with functional recovery.

The study of spinal cord regeneration in the phylogenetic scale is likely to help us in the understanding of the problem in the human situation. After spinal transection in lizards, histological changes in the spinal cord were studied and correlated with functional recovery. Some changes in spinal cord, suggestive of regeneration between the two stumps were observed. The recovery of function did not appear to be dependent on synaptic continuity.

Surface epithelial tumours of the ovary.

Surface epithelial tumours (SET) constituted 65.7% of all the ovarian tumours. Benign tumours were 182 (71.9%), of low malignant potential (LMP) 11 (4.4%) and frank malignant 60 (23.7%). Maximum number of cases, 102 (40.3%) belonged to 3rd decade. Mean age for serous cystoma was 31.5% years as compared to 30.8 years for mucinous cystoma. The commonest presenting feature was the abdominal lump observed in 182 cases (71.9%) and pain in abdomen in 120 (47.4%).Serous cystomas were t he most frequent tumours and comprised of 32.21% of all the ovarian tumours or 46.01% of all the SET or 65.56% of all the cystic SET. Seventeen (11.7%) of serous tumours were bilateral. Mucinous cystomas constituted 14.55% of all the ovarian tumours or 30.8% of all the SET. These tumours were bulky (78.6%; 15 cm diameter) and multilocular (83.9%).Mucinous cystadenocarcinoma was the commonest malignant epithelial tum our (36.6%). Endometroid carcinoma comprised 3.65% of all the SET or 8.4% of all the ovarian malignancy. Squamous metaplasia was seen in one case whereas 2 cases were of mesodermal mixed tumour with heterologous element as rhabdomyosarcoma. Clear cell carcinoma, Brenner tumour and unclassified group constituted 0.79%, 1.18% and 1.58% of all SET respectively.

A histomorphologic and ultrastructural study of the malignant tumours of the renal pelvis.

The study was carried at two different centres. Only 9 cases of primary malignant tumours of the renal pelvis could be collected during the period of 7 years (1984-1990). Renal pelvis malignancies constituted 0.21% of all the malignancies and 12.16% of all the malignant growths of the kidney (9 out of 74 cases). The age of these patients ranged from 24 to 70 years; the mean being 41.7 years. Male/female ratio was 8:1. Common triad of complaints (pain, haematuria and lump) was noticed in 22.2% of patients. Individually they were noticed in 77.8%, 66.7% and 44.4% of patients respectively. Transitional cell carcinoma was the commonest, seen in 7 patients (77.8%) whereas squamous cell carcinoma and adenocarcinoma were noticed in one patient (11.1%) each. Hydronephrosis, chronic pyelonephritis and nephrolithiasis were noticed in 66.7%, 44.4% and 22.2% of patients respectively. Ultrastructural study of urothelial tumours revealed tumour cells in various stages of differentiation with loss of intercellular junctions and dense collection of rough endopasmic reticulum fibrils around the nucleus.

Double malignancy in a benign cystic teratoma of the ovary (a case report).

A case of malignant change in a benign cystic tertoma of the ovary has been reported where there was double malignancy. Leiomyosarcoma was associated with squamous cell carcinoma (In situ). The patient remained well for one year after ovariotomy.

Solid tumours of the ovary.

One hundred seventeen solid ovarian tumours, diagnosed histologically during the period between 1971 and 1990, were studied. The overall incidence of solid ovarian tumours was 23.4% of all the ovarian tumours (500 cases) studied. Of 117 solid ovarian tumours 19 (16.2%) were benign and the rest 98 (83.8%) were malignant. Epithelial tumours were the commonest (28.2%) followed by germ cell tumours (22.2%), sex cord stromal tumours (21.4%), metastatic tumours (19.7%) and non-specific tumours (8.5%). The average age (26.8 years) was comparatively low for germ cell tumours otherwise in other groups it ranged between 42 and 45 years. Below 15 years immature teratoma was diagnosed in 4 cases and granulosa cell tumour in 2 cases. Bilateral tumours were seen in 22 cases (23.2%) out of 95 cases observed. Pain and fullness in the pelvic region were observed in 94.9% cases. Varied morphological picture was seen in 6 cases of endometrioid carcinoma. Dysgerminoma constituted 6.8% of solid ovarian tumours. Gliomatosis peritonei was noticed in one case of immature teratoma. Granulosa cell tumour accounted for 11.1% of solid ovarian tumours. Of 23 cases of metastatic tumours, Krukenberg tumour was noticed in 88.9% cases. Diagnostic problems as well as prognostic factors of solid ovarian tumours have been discussed.

Clinical utility and monitoring of breast cancer by circulating immune complexes.

Circulating immune complexes (CIC) were estimated in 22 patients of breast carcinoma, 25 healthy control volunteers and 10 follow-up cases after mastectomy by polyethylene glycol precipitation (PEG pptn) test and Latex agglutination inhibition (LAI) test. CIC levels increased with advancing stage of breast carcinoma. Significant increase in CIC levels was observed in stage II (p < 0.01), followed by highly significant increase in stage III and IV (p < 0.01) as compared to the control group. Sharp decrease in CIC levels was observed three months after radical surgery in 9 post-operative patients. One patient remained seropositive by both tests, followed by a fatal outcome after four months follow-up. Seropositivity for CIC by PEG pptn test in patients of breast carcinoma was 72.72 percent as compared to 81.81 percent by LAI test. Combination of both tests increased total CIC positivity by 90.9 percent. Clinical utility and prognostic significance of CIC in monitoring breast carcinoma patients has been demonstrated by our study.

Primary malignant lymphoma of the gastro-intestinal tract: a clinicopathological study of 24 cases.

Twenty-four cases of primary lymphoma of the gastro-intestinal tract were diagnosed during the period 1970 to 1991. There was a preponderance of males and the male to female ratio being 1.4:1. Age ranged from 9-70 years, mean 32.2 years. Small intestine was involved in 50% cases, large bowel in 9 cases (37.5%) and stomach in 3 cases (12.5%). There were 5 cases (20.8%) of Hodgkin's disease and 19 cases (79.2%) were of non-Hodgkin's lymphoma. All cases of gastric lymphoma complained of epigastric pain, weight loss and vomiting. In lymphoma of small intestine, 8 patients complained of pain associated with vomiting and 6 patients complained of distension of abdomen. In large bowel lymphoma, pain in right iliac fossa was complained by 4 patients and bleeding per rectum by 3 patients. Out of all the 24 cases, changes in bowel habit were noted in 15 patients and occult blood was positive in 13 cases. Palpable abdominal mass was noted in 14 patients. Histomorphologically, all the 3 cases in the stomach were of lymphocytic lymphoma diffuse type. Out of 19 non-Hodgkin's lymphoma, 15 were of lymphocytic lymphoma and 4 were of histiocytic lymphoma.

Morphological changes in diseased gall bladder: a study of 415 cholecystectomies at Aligarh.

Morphological changes of gall bladder were studied in 415 cholecystectomy specimens. There was a preponderance of females (male to female ratio--1:6.5). The mean age of the cases was 43.6 years. Most of the cases (63.4%) were in the 4th and 5th decades of life. The average duration of illness was 2.8 years. Associated cholelithiasis was present in 85.3% cases. Gall-stones were of mixed variety in 78.2% cases, cholesterol type in 15.3% cases and both types were present in 6.5% cases. Chronic cholecystitis was the main histological diagnosis (50.8%). Other lesions observed were adenomyomatosis (8.2%), adenomatous hyperplasia (10.1%), granulomatous cholecystitis (4.1%), cholesterosis (2.7%), acute cholecystitis (4.1%), acute on chronic infection (10.8%), sub-acute cholecystitis (2.4%) and carcinoma gall bladder (6.8%). The frequency of Rokitansky-Aschoff's sinuses was closely related with the degree of inflammatory response. In 13 (6.2%) cases the diagnosis of chronic follicular cholecystitis was made. All the cases of cholesterosis were multiparous females and of younger age. Of the malignant lesions, adenocarcinoma was the commonest (96.4%).

Stromal cellular response in breast tumours and allied lesions.

Histopathological study for stromal cellular response was made on 200 cases of benign and dysplastic lesions and malignancy of breast. Infiltrations with lymphocytes and plasma cells were observed in 64% cases of fibroadenoma, 66.6% cases of giant fibroadenoma, 61% cases of mammary dysplasia and 33.3% cases of gynaecomastia. While mast cell infiltration was not observed in giant fibroadenoma, its presence was observed in 92% cases of fibroadenoma, 77.8% cases of mammary dysplasia and 33.3% cases of gynaecomastia. Lymphocytes and plasma cells infiltrations were observed in 100% of cases of invasive duct carcinoma, medullary carcinoma and fibrosarcoma. Comedocarcinoma showed infiltration with these cells in 75% of cases while that for colloid carcinoma and Paget's disease of breast were observed in 50% of cases of each. Infiltrations with mast cells were observed in 92.3% cases of invasive duct carcinoma, 75% cases of comedocarcinoma and 25% cases of medullary carcinoma. Other malignant conditions of breast did not show mast cell infiltration. Degree of infiltration with lymphocytes and plasma cells was mainly of low grade in benign and dysplastic lesions compared to high degree of infiltration in malignancy. Mast cell infiltration was of low degree in both the types of lesions.
