Scrotal calcinosis effect - Case report and review of literature.

Idiopathic scrotal calcinosis is a benign rare diseases that is characterized by single or multiple scrotal skin calcified nodules without evidence of systemic disease. We report the first case in Saudi Arabia of Idiopathic scrotal calcinosis in a patient whose a 42 years old male, medically and surgically free who presented to our clinic with multiple scrotal nodular lesions in which excision was done and histology showed calcium deposition in basophilic globules which is consistent with Idiopathic scrotal calcinosis. Although pathogenesis and etiology of Idiopathic scrotal calcinosis is controversial, surgical excision is the treatment of choice.

Spontaneous Pneumothorax in an Elderly Patient With Coronavirus Disease (COVID-19) Pneumonia.

The relationship between the 2019 novel coronavirus (COVID-19) and pneumothorax is not yet established. As of June 2020, few cases of nonintubated patients developing pneumothorax had been documented. We present the case of an elderly patient with COVID-19 pneumonia that resulted in a prolonged hospital course because of pneumothorax complication.

Phosphaturic mesenchymal tumor: a report of 6 patients treated at a single institution and comparison with reported series.

Osteogenic osteomalacia (OO)-associated phosphaturic mesenchymal tumors (PMTs) might represent a single histopathologic paraneoplastic entity. These tumors are largely misunderstood, ignored, or unknown by pathologists and clinicians. To elucidate the characteristics of OO-associated PMTs, we retrospectively analyzed the clinicopathologic features of PMTs from 6 patients, with either known OO or features suggestive of PMT-mixed connective tissue variant, who were studied and managed at a single center during the period from 1993 to 2011.

Malignant granular cell tumor: case report with a novel karyotype and review of the literature.

Malignant granular cell tumor is a rare neoplasm reported to occur at various sites in the body. Histogenesis of these tumors is still vaguely understood; however, their metastatic potential and adverse prognosis is well-described in the literature. The histologic criteria of malignancy proposed by Fanburg-Smith et al are still debatable amongst pathologists, with metastasis being the sole criterion of malignancy with unanimous agreement.
