Clinicohematological Study of Pancytopenia in a Tertiary Care Hospital of Western Region of Nepal.

INTRODUCTION: Pancytopenia is a relatively common hematological entity and is a manifestation of many illnesses which can be life threatening at times. The severity of pancytopenia and the underlying pathology determine the management and prognosis. This study was conducted to evaluate hematological and bone marrow findings in patients presenting with pancytopenia. METHODS: A prospective observational study was conducted in Department of Pathology, Manipal College of Medical Sciences, Pokhara from January 2011 to December 2016. Clinical and hematological parameters including bone marrow aspiration and biopsy were evaluated in all patients who presented with pancytopenia. RESULTS: Among 138 cases studied, patients' age ranged from 2 to 82 years with a mean age of 43.95 years, and there was male predominance. Most of the patients presented with generalized weakness, pallor, dypnoea and fever. Hypoplastic marrow was seen in 38 (27.5%) cases, followed by 26 (18.8%) cases of megaloblastic anemia and 19 (13.76%) cases of acute leukemia. Other findings included one case each of hemophagocyosis, leishmaniasis, plasmodium vivex malaria and metastatic carcinoma. CONCLUSIONS: This study highlights that pancytopenia is a common hematological problem and that the study of detailed primary hematological investigations along with bone marrow study in patients with pancytopenia will help to identify the cause for further planning and management.

Squamous cell carcinoma arising in familial gingival fibromatosis-a rare case report.

Familial gingival fibromatosis is a rare hereditary condition due to chromosomal abnormality which can occur as an isolated disease or as part of a syndrome and has an incidence of 1:350 000. This condition leads to esthetic, functional, psychological and masticatory disturbance of the oral cavity. Here, we present a case of 21-year-old female with severe enlargement of gums in maxilla and mandible. Deciduous teeth were erupted at normal age but the permanent teeth in the oral cavity were not erupted. Her grandmother, father and younger sister were also affected with the same condition. Incisional biopsy from the chronic ulcerated gingiva showed squamous cell carcinoma. Patient was referred to other cancer institution, where metastases to lung, bone and lymph node was detected on CT scan. The diagnosis was made based on clinical examination, family history and histopathological examination.

Warty Carcinoma Penis: An Uncommon Variant.

Penile carcinoma frequency varies widely in different parts of the world and comprises 1-10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%-10% of all the variants. The other histological variants include basaloid, verrucous, papillary, sarcomatous, mixed, and adenosquamous carcinoma. The various histological entities with an exophytic papillary lesions including warty carcinoma are together referred to as the "verruciform" group of neoplasms. The warty carcinoma has to be differentiated from these lesions and is typically distinguished by histological features of hyperkeratosis, arborescent papillomatosis, acanthosis, and prominent koilocytosis with nuclear pleomorphism. We present a case of 65-year-old male with growth measuring 6 × 4 cm in the penis who underwent total penectomy and was diagnosed as warty carcinoma penis.

Basal Cell Carcinoma in Cases with or without Xeroderma Pigmentosum.

INTRODUCTION: Basal cell carcinoma is the most common form of cancer in humans and comprises the vast majority of skin cancers. It predominantly affects fair-skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. METHODS: A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. RESULTS: This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. CONCLUSIONS: Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions.

Value of image-guided fine-needle aspiration cytology-a study of 500 cases.

Guided Fine-Needle Aspiration Cytology (FNAC) as the first line investigation is not only useful in diagnosis of space occupying lesions but can also help in choosing appropriate management. This technique is most useful in diagnosing metastasis but is also helpful in excluding malignancy in some cases. Aim of this study is to analyze the spectrum of cytological diagnosis, adequacy, and clinicoradiological correlation of guided FNAC. The study was carried out in the departments of pathology and radiology for a period from January 2000 to November 2011. All the data were retrieved from hospital medical record section and departmental data bank and were analyzed. We have performed a total of 500 FNACs, including 234 under CT guidance and 266 under USG guidance. Among the CT-guided FNACs, 87.6% (205 cases) had adequate material which included 152 malignant cases, 38 inflammatory cases and 15 benign cases. Among the cases under USG, 91.7% (244 cases) had adequate material comprising of 112 malignant cases, 44 inflammatory cases, and 88 benign lesions. It was noted that increased number of inadequate aspirate was from lesions with smaller size and increased depth. Out of total 264 malignant cases diagnosed on FNAC, 160 cases were identified as malignant on clinical and radiological findings. Guided FNAC is useful in deep seated lesions as well as in suspicious superficial lesions and is a safe diagnostic tool. If performed properly and correlated well with clinical and radiological findings, FNAC provides correct diagnosis in most cases.

Biological behavior of preneoplastic conditions of the endometrium: A retrospective 16-year study in south India.

BACKGROUND: THE BIOLOGICAL BEHAVIOR OF ENDOMETRIAL CARCINOMA DIFFERS IN EPIDEMIOLOGY, PRESENTATION, AND PROGNOSIS, SUGGESTING THAT THERE ARE TWO FUNDAMENTALLY DIFFERENT PATHOGENIC TYPES OF DISEASE: type I (estrogen related, endometrioid type) and type II (non-estrogen related, non-endometrioid type). Untreated hyperplasia can develop into an endometrioid type of adenocarcinoma, hence, it is important to recognize the former type. In contrast to cervical cancers, there are limited studies with respect to the biology of hyperplastic lesions documented from India. This was a 16-year retrospective study, carried out to determine the nature and outcome of proliferative lesions of the endometrium in a referral center from south India. MATERIALS AND METHODS: A histopathological diagnosis of the endometrial hyperplasia, polyp, and carcinoma, on endometrial biopsy and hysterectomy specimens, over a 16 year period (1983 to 1999), were recorded in a computer and the case slides were reviewed. Using the computer software Foxpro, the patients who had come more than once for a subsequent or previous biopsy were identified. An attempt was made to look for progression, regression or a static nature of the lesion in the follow-up cases. RESULTS: A total of 1778 cases were studied, and only 74 patients with endometrial hyperplasia and five cases of benign endometrial polyp had follow-up endometrial histopathology. Hyperplasia cases included 59 cases of simple hyperplasia, 10 cases of complex hyperplasia without atypia, and five cases with atypia. The predominant age for patients with all types of hyperplasias was 41 - 50 years. Progression to a higher grade was seen in 8.10%, regression to a lower grade was seen in 9.45%, lesions reverted to a normal pattern in 10.81% cases, and lesions persisted in 70.27% of the cases. A mixed pattern was seen in 54 cases, with predominant coexistent lesion being simple and complex hyperplasia without atypia. CONCLUSION: The fate of the hyperplastic lesion of the endometrium showed a varied pattern. Follow-up cases predominantly showed persistence of the lesion, possibly resulting from a fluctuating but higher level of estrogenic stimulus. Hence, it was not only the high levels of estrogen that influenced the biology, but its sustenance for a prolonged period.

Delay in surgery for acute appendicitis.

BACKGROUND: The present study investigates the effect of delay in appendicectomy on the outcome of surgery and also examines the contribution of patient and physician related delay to the stage of appendicitis. METHODS: During a 12-month period, 114 consecutive adult patients undergoing appendicectomy for acute appendicitis were monitored prospectively. Time of onset of symptoms, presentation to the hospital, surgery consultation, decision to operate and starting of surgery were all noted. The stage of the appendicitis was identified based on operative findings and pathology reports. Postoperative events were recorded. The stage of appendicitis and outcome were related to the prehospital and in-hospital delay of each patient. RESULTS: There were three (2.6%) normal, 62 (54.4%) early inflamed and 49 (43%) cases of advanced appendicitis. The total delay from onset of symptoms to performance of appendicectomy was 2.4 times longer in the advanced appendicitis group than in the early inflamed appendicitis group. There was no significant difference in the in-hospital delay between the two groups. Delay in the resumption of oral feed and total hospital stay were significantly higher in the advanced appendicitis group. CONCLUSIONS: The present prospective study concludes that morbidity caused by acute appendicitis correlates directly with delay in treatment. In the majority of cases the delay in treatment is predominantly caused by patient related factors. The negative appendicectomy rate can be reduced by close observation of cases with clinical uncertainty without increasing the morbidity.
