Analysis of karyometric variables in spontaneously occurring canine mammary tumors.

OBJECTIVE: To study alteration in karyometric variables to distinguish benign from malignant canine mammary tumors. STUDY DESIGN: Formalin-fixed, paraffin-embedded tissue sections from 16 cases of canine mammary tumors were stained with hematoxylin-eosin and analyzed for mean nuclear area, mean nuclear perimeter and shape factor. The morphometric descriptors were then correlated with conventional histologic diagnosis. RESULTS: On Mann-Whitney U-test, nuclear variables, that is, mean nuclear area and mean nuclear perimeter, revealed significant difference between malignant and benign groups (p < 0.01), while shape factor showed significant difference at p < 0.05. All morphometric descriptors showed significant correlation with each other and with histopathologic diagnosis. Contrary to expectations, shape factor was lower in benign compared to malignant tumors. In benign mammary tumors, the highest mean nuclear area and perimeter were 39.59 +/- 10.34 microm2 and 25.39 +/- 4.14 microm, respectively, for fibroadenoma; and in malignant tumors the highest mean nuclear area and perimeter were 48.44 +/- 12.89 microm2 and 27.36 +/- 4.31 microm, respectively, for papillary adenocarcinoma. CONCLUSION: This study provides insight into the alterations in karyometric variables in canine mammary tumors. Mean nuclear area and perimeter appear to have potential to differentiate benign and malignant canine mammary tumors.

Germ cell tumors of the ovary: a clinicopathologic study of 121 cases from Nepal.

BACKGROUND: Although many reports have been published about germ cell tumors of the ovary in developed countries, there has been no such documentation from Nepal. The retrospective study presented here reports the clinicopathologic profile of germ cell tumors of the ovary studied at B. P. Koirala Institute of Health Sciences, Dharan, Nepal. METHODS: A retrospective analysis of 121 histopathologically proven cases of germ cell tumor of the ovary operated on at either our institute or somewhere else (but processed in our institute) from November 1995 to April 2001 (5.5 years) was done. Clinical data, histopathologic findings and complications were recorded. RESULTS: The prevalence of germ cell tumors was 43.36% (121/279) of all ovarian neoplasms. Patient age varied from 8 to 65 years (median 31 years). Tumor occurrence was most frequent in patients aged 21-40 years. Only eight of 121 cases (6.61%) were malignant; the rest (93.39%) were mature teratomas. Of great interest was the unexpectedly high number of cases (47.93%) found in patients who were hill natives such as Rai and Gurung. Pain and abdominal fullness were common symptoms noted in 85.95% and 79.31% of patients, respectively. Seventeen (14%) asymptomatic cases were found either on routine physical examination (12 cases) or during pregnancy (five cases). The left ovary was involved in 39.7% cases and the right in 35.5%. Bilateral involvement was seen in 24.8% of cases. Torsion was noted in 20.66% and was the most common complication. Of all the germ cell tumors 93.39% were cystic and only 6.61% were solid on gross appearance. There were three cases of monodermal benign teratoma, four cases of immature teratoma and one case of malignant transformation. CONCLUSION: Mature teratoma is the most common germ cell tumor and accounts for 40.50% of all ovarian neoplasms. The high prevalence of germ cell tumors of the ovary found among patients who were hill natives needs to be explored further.

Pure red cell aplasia--report of 11 cases from eastern Nepal.

There were eleven cases of pure red cell aplasia diagnosed over a period of 2 years (January 2000-December 2001). All the patients had anemia with pallor and weakness being the presenting complaints. Hematological profile depicted normocytic normochromic anemia, reticulocytopenia and marked paucity of erythroid precursors on bone marrow aspiration and biopsy studies. In the present study, one case was of congenital pure red cell aplasia, in one other case of pyrexia of unknown origin, no definitive diagnosis could be made. Other associated diseases seen with pure red cell aplasia were thymoma, septicemia, protein energy malnutrition, non-Hodgkin's lymphoma, juvenile rheumatoid arthritis, acute myeloid leukemia, tuberculosis and hepatitis C. The association of pure red cell aplasia with haematologic malignancies is rare. There are very few case reports on pure red cell aplasia with hepatitis C.

Ulcerative post-kala azar mucosal leishmaniasis masquerading as a carcinoma--a case report.

Post kala-azar mucosal leishmaniasis (PKML) is relatively rare in the Indian subcontinent. We describe an ulcerative variant of PKML with nasal involvement in a Nepalese adult male. He had ulcerated plaque over the upper lip with extensive involvement of nasal columella and septum. He came from endemic area for kala-azar and had a previous history of kala-azar. There were plenty of LD bodies in microsections and FNA of submandibular lymph node.

Massive cystic degeneration of a uterine leiomyoma presenting as an ovarian cyst: a case report.

An unusual case of massive cystic degeneration in an uterine leiomyoma measuring 21 cm in diameter, in a 40 year old female is being presented. It was diagnosed as a cystic adnexal tumor on ultrasonogram. Interlacing bundles of smooth muscle were identified in the cyst wall, which was confirmed on special stains. The differential diagnoses considered in this case are discussed. To the best of our knowledge, this is the largest cystic degeneration in an uterine leiomyoma reported in the literature.

Chromoblastomycosis: report of two cases from Nepal.

Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissue caused by dematiaceous fungi. The first case, a 67-year-old male farmer, presented with itchy hyperkeratotic, scaly plaques with scarring and black dots on the lateral aspects of his left arm and dorsum of his left hand of 28 years duration. The case was clinically diagnosed as chromoblastomycosis. The second case, a 75-year-old farmer, presented with erythematous, crusted, scaly plaques on the dorsum of the left foot of 30 years duration. Initially, a clinical diagnosis of lupus vulgaris was made, but treatment with anti tuberculosis therapy showed no improvement. On the basis of histopathological examinations of skin biopsies and isolation of fungus on culture, both cases were diagnosed as chromoblastomycosis. To the best of our knowledge, these two cases are the first case reports of chromoblastomycosis from Nepal and are presented for their academic interest.

Mucinous carcinoma of rectosigmoid in a 15-year-old child: a case report.

A 15-year-old girl with Duke's B mucinous carcinoma of the rectosigmoid was treated with surgical resection and adjuvant chemotherapy. The patient is alive and has been disease-free for 15 months. Colorectal carcinoma is extremely rare in children and adolescents. Adenocarcinoma of colon is a virulent disease in children and has a poor prognosis. This is because of the poor histological characteristics and difficulty in diagnosis.

Acute appendicitis: a quality assurance study.

The parameters that indicate the quality of patient care in acute appendicits (AA) were evaluated. One hundred sixty-four patients, who underwent emergency appendectomy (EA) at the B.P. Koirala Institute of Health Sciences, Dharan, Nepal were studied prospectively. The mean duration of the symptoms was 42.2 +/- 69.5 hours (range 2-720 hours, median 24 hours). The mean waiting period in the hospital was as 12.7 +/- 21.8 hours (range 1-188 hours, median 7 hours). Special investigations' such ultrasonography, computed tomography or laparoscopy, were not used for diagnosis. The perforation rate was 39%. The histopathology report of 79% of the patients was available. Diagnostic accuracy in histologically evaluated patients was 91.5%. One patient (0.6%) died. The mean hospital stay was 3.2 +/- 2.0 days (range 1-17 days). Patients who had to wait in hospital for < 24 hours before surgery had a longer duration of symptoms, underwent exploratory laparotomy through a mid-line incision more frequently, had a higher incidence of perforated/gangrenous appendix and longer hospital stay. The mean medical expenditure for patients treated in the general ward was Nepali Rupees (NR) 2485 +/- 504 (range NR 1372-4500). The majority of patients/guardians (88%-97%) were satisfied with the medical expenditure incurred, promptness of service, behaviour of the hospital staff and the facilities available in the hospital. The diagnostic accuracy and cost of treatment were favourable. The longer duration of symptoms, non-utilization of special investigations for diagnosis, high perforation rate and less than cent-per cent biopsy rate are the aspects that require attention to improve the quality of surgical care.
