An institutional experience of hydatidosis and cysticercosis in Nepal: a retrospective chart review.

This study aimed to investigate the demographic characteristics, anatomical distribution, and histopathological features of hydatidosis and cysticercosis in a Nepalese population presenting to a tertiary care hospital. The study also aimed to provide a better understanding of the clinical and pathological aspects of these diseases in the local context. Methods: This retrospective study analyzed all cases of hydatidosis and cysticercosis reported in the Department of Pathology at Tribhuvan University Teaching Hospital between January 2013 and December 2019. Demographic, clinical, radiological, and histopathological data were collected and analyzed from hospital charts. Results: During the 7-year study period, the authors identified 112 cases of hydatid cysts and 26 cases of cysticercosis. The mean age of patients with hydatidosis was 33.86 years (range: 5-74 years), while the mean age of patients with cysticercosis was 25.39 years (range: 4-63 years). Females were more commonly affected with hydatidosis (68, 61.7%) than males (44, 39.3%), resulting in a male-to-female ratio of 0.6:1. In contrast, there was no significant sex difference in cysticercosis cases, with 14 (53.85%) males and 12 (46.15%) females affected. The most commonly affected site for hydatid cysts was the lung (47 cases, 42%), followed by the liver (41 cases, 36.6%). The study identified three cases of neurocysticercosis. The average diameter of hydatid cysts and cysticercosis was 8.7 cm and 1.7 cm, respectively. Conclusion: In conclusion, our study provides important insights into the clinical and pathological features of hydatidosis and cysticercosis in a Nepalese population. These zoonotic diseases pose a significant health burden, particularly among the poor and marginalized populations. Our findings highlight the need to integrate prevention and control measures into the healthcare system to decrease the overall burden of these diseases.

Sinonasal mucosal melanoma presenting as a maxillary sinus mass: A case report.

Maxillary sinus melanoma is a rare mucosal melanoma difficult to diagnose in the absence of pigmentation. Intranasal masses presenting with the features of occult malignancy and rapid progression should always be investigated in the line of melanoma irrespective of pigmentation. The histopathological and immunohistochemical examination helps to confirm the diagnosis.

Keratosis obturans: A rare cause of facial nerve palsy.

Keratosis obturans, caused by the deposition of desquamated keratin plug in the external auditory canal can present with facial palsy. Young patients presenting with facial palsy, earache, and gradual hearing loss should be suspected for Keratosis obturans.

EDTA-dependent pseudo thrombocytopenia mimicking dengue fever-associated persistent thrombocytopenia: A case report.

No hemorrhagic manifestations, presence of platelet clumps on the peripheral blood smear, normal manual count, and normal autoanalyzer count after collecting blood in citrate vial help confirm the diagnosis of EDTA-dependent thrombocytopenia.

Kikuchi-Fujimoto disease: A rare case report from Nepal.

Clinicians and pathologists must be aware of the occurrence of Kikuchi-Fujimoto Disease, as one of the differential diagnoses of cervical lymphadenopathy.

Multiple jejunal gastrointestinal stromal tumors and Neurofibromatosis type 1: A rare association.

INTRODUCTION AND IMPORTANCE: The association between gastrointestinal stromal tumor (GIST), mesenchymal tumor arising from the interstitial cells of cajal and Neurofibromatosis type 1 (NF1), an autosomal dominant disease has been reported in the literature. GIST in NF1 patients are multiple and located in the small intestine. Tumorigenesis in NF1 associated GIST is different to that of sporadic GIST and hence the treatment. Here we report a rare case of an NF1 patient with multiple jejunal GISTs. CASE PRESENTATION: We here present a rare case of a 57-year-old male diagnosed with NF1 30 years back, presented in our emergency department with complaints of black, tarry stools later diagnosed to have multiple GIST in jejunum. Contrast enhanced computed tomography (CECT) of the abdomen showed a large 10.1 × 7.33 × 6.2 cm heterogeneous, exophytic, solid mass with cystic areas originating from the jejunum. The microscopic examination of the specimen showed spindle shaped tumor cells while immunohistochemistry showed CD117 (c-KIT) and DOG-1 positivity. The primary treatment was complete surgical excision of the tumor. CLINICAL DISCUSSION: The incidence of GISTs in NF1 patient is around 6-7%; however, concomitant presence of multiple GISTs is rare. CECT of abdomen along with histopathological and immunohistochemistry studies are diagnostic. The management of GIST includes surgical and adjuvant therapy methods based on the tumorigenesis and recurrent risk stratification. CONCLUSION: Early clinical suspicion and imaging aids in early detection of the tumor in patients with NF1 presenting with gastrointestinal symptoms. Postoperatively, screening for recurrence with radiology is of utmost importance.
