Progressive external ophthalmoplegia - A case report.

Progressive external ophthalmoplegia is a slowly progressive hereditary mitochondrial myopathy. Most mitochondrial disorders overlap clinically, enzymatically, and genetically. The most common enzyme defect is the combined deficit of complexes I and IV. Progressive external ophthalmoplegia particularly affects the extraocular muscles and is characterised by ophthalmoplegia, and bilateral ptosis. The ptosis and ophthalmoplegia is unresponsive to anticholinergics, with no effective treatment, but corrective surgery for ptosis as a palliative one. In this article, we report a rare case of a 16-year-old female with characterstic histological features consistent with progressive external ophthalmoplegia.

Cytomorphological Spectrum of Malignant Melanoma: A 3-Year Study in a Tertiary Care Centre in India.

Background: Melanoma is an aggressive malignant tumor with high metastatic potential. FNAC provides a quick and effective tool to diagnose primary and metastatic melanoma cases. Aims and Objectives: To document the epidemiological features of malignant melanoma cases attending in a tertiary care centre in India, with special reference to different cytomorphological parameters. Materials and Methods: This was a retrospective hospital based study done in the Department of Pathology. 39 cases of malignant melanoma diagnosed on cytology during a period of 3 years were retrieved, reviewed and studied. Results: Out of the 39 cases,21 were males(1.16 male:female ratio). The mean age was 53 years. Metastatic cases were more common than primary melanoma cases. Most common site for metastasis was liver followed by inguinal lymph node. Epitheloid was the most common pattern. Conclusion: Characterstic melanin pigment although common, is not always present. Thus, cytopathologists must know the various cytomorphological spectrum of features of melanoma.

Acute pancreatitis masquerading as mesentric growth in COVID-19 patient: A case report.

COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It commonly affects the respiratory system, producing pneumonia-like symptoms. Among extrapulmonary manifestations, involvement of the gastrointestinal tract is common with symptoms of nausea, vomiting, diarrhea, and abdominal pain. Coronavirus acts by targeting the ACE-2 receptors in the alveoli of the lungs, but because these receptors are also present in other organs, such as the pancreas, it can affect the pancreas as well, thus causing acute pancreatitis. We here discuss a case of a 72-year-old hypertensive male with COVID-19 who presented with atypical presentation of acute abdominal pain and a few episodes of vomiting. Laboratory investigations were inconclusive. Imaging findings were suggestive of small bowel obstruction and perforation; thus, an exploratory laparotomy was done in which a mesenteric growth was found, reported as acute pancreatitis on histopathology. Therefore, attention should be paid to the pancreatic involvement and atypical presentations in COVID-19 patients.

Orbital magnetic resonance imaging profile and clinicoradiological correlation in COVID-19-associated rhino-orbital-cerebral mucormycosis: A single-center study of 270 patients from North India.

PURPOSE: To study the clinical profile and magnetic resonance imaging (MRI) features in patients of COVID-19-associated rhino-orbital-cerebral mucormycosis (CA-ROCM) with orbital involvement and perform a clinicoradiological correlation. METHODS: A cross-sectional study was performed at a tertiary care center in north India from May 2021 to June 2021. Consecutive patients with clinical, nasal endoscopic, and/or microbiological evidence of CA-ROCM underwent MRI of paranasal sinuses, orbit, and brain as per the study protocol. Orbital MRI findings were studied in detail and were correlated with clinical signs. RESULTS: Two hundred and seventy patients were studied. The mean age was 48.4 (± 16.82) years. A male predilection was noted (male:female = 1.77). Orbital involvement was seen in 146 (54%) patients on clinical evaluation and in 184 (68%) patients on MRI. Unilateral orbital involvement was more common (134; 92%). The most common presenting symptom was periorbital and/or facial pain (141; 52.2%) and the most common clinical sign was periorbital edema (116; 43%). The most common MRI finding was suggestive of orbital cellulitis (160; 59%). Orbital compartment syndrome was found in 17 (6.3%) patients. The inter-rater agreement between clinical and radiological assessments to detect the involvement of infraorbital nerve and frontal nerve was found to be 85.56%, (κ 0.621) and 93.70% (κ 0.776), respectively. The diagnostic accuracy, sensitivity, and specificity of MRI to detect medial orbital wall defect were found to be 87.9%, 65%, and 97%, respectively. CONCLUSION: Orbital imaging features of a cohort of ROCM patients have been presented with clinicoradiological correlation.
