[Two Case of Rhino-Orbito-Cerebral Mucormicosis Developed After COVID-19 Infection].

Coronavirus 2019 (COVID-19) infection causes excessive cytokine response and a decrease in cellular immune response and this increases susceptibility to fungal co-infections. Mucormycosis is a rare, lifethreatening invasive fungal infection. In this report, two cases who developed rhino-orbito-cerebral mucormycosis shortly after having COVID-19 infection were presented.

A case of mediastinal mesenchymal tumor resembling hemopericardium.

Mediastinal neoplasms are rare in the elderly, and clinical suspicion is the first and most important step of differential diagnosis. Mediastinal tumors can be misdiagnosed because their symptoms or signs can overlap with cardiovascular diseases, which have a higher prevalence among the older population. The diagnostic process should be managed with multimodality imaging and clinical judgement.

Pediatric Mass Lesions of the Head and Neck Region and Fine-Needle Aspiration Biopsy Results.

Objective: 1. To provide a classification of pediatric mass of the head and neck region and evaluate their frequency. 2.

A rarely seen diffuse parenchymal lung disease: diffuse pulmonary meningotheliomatosis.

Pulmonary meningothelial-like nodules (MLNs) are usually detected incidentally during pathologic evaluation of resected pulmonary parenchymal specimens and autopsies. These nodules are generally asymptomatic and most often single. Diffuse pulmonary involvement by MLNs is less frequently described.

Tonsillar leiomyosarcoma.

Unlabelled: Leiomyosarcomas of the head and neck is an extremely rare entity that because of its infrequency has been associated with both delayed diagnosis and misdiagnosis. Sinonasal tract is the most common site in this region. The overall prognosis is poor.

Congenital leiomyoma of the distal ileum associated with ileal atresia: a case report.

Association of distal ileal atresia with leiomyoma is a quite rare condition. Herein, we describe a newborn who underwent surgery for ileal atresia and was found to have leiomyoma on pathological examination in the atretic segment. The presence of leiomyoma may indicate a malformation during recanalization and could play a role in the etiology of intestinal atresia.

Retroperitoneal malignant fibrous histiocytoma can mimic a hydatid cyst.

Malignant fibrous histiocytoma is the second most common soft-tissue sarcoma in adults. After the extremities, the retroperitoneal space is the second most common site of this tumor. A 50-year-old man presented with a right retroperitoneal, thick-walled, cystic multilocular mass measuring 10 × 10 cm that was thought to be a type CE 5 hydatid cyst preoperatively.
