Skin disorders associated with the COVID-19 pandemic: A review.

INTRODUCTION: In December 2019, a new coronavirus has emerged out of China, the SARS-CoV-2 virus, causing a disease known as COVID-19, which steadily has progressed into a pandemic. This coronavirus affects many organs, including the skin, whose manifestations are a consequence of the disease itself, as well as the preventative measures taken to avoid the infection. This paper reviews the cutaneous manifestations which currently have been encountered during this pandemic. METHODS: A search was conducted on PubMed, and all relevant articles were included. RESULTS: The results show the occurrence of many cutaneous findings, ranging from those related to the infection itself and to various dermatitides related to the use of personal protective equipment (PPE) utilized by healthcare workers while attending to infected patients. DISCUSSION: Recognizing these findings is important for the accurate diagnosis of those infected with COVID-19 as well as the prompt treatment of the side effects caused by PPE that might further impair the effectiveness of healthcare workers.

Liver resection for metastatic colorectal leiomyosarcoma: a single center experience.

BACKGROUND: Leiomyosarcoma arising in the colorectum is a rare malignancy of the smooth muscles accounting for less than 1% of gastrointestinal tumors. Surgery remains the most accepted modality for the treatment of this entity however management of liver metastases remains controversial. METHODS & RESULTS: From 1998 to 2009, five patients diagnosed with primary leiomyosarcoma of colorectal origin with metastatic liver disease, underwent liver resections at the American University of Beirut Medical Center. The median overall survival was 47 months (range, 7-135 months). CONCLUSIONS: Leiomyosarcoma of colorectal origin with liver metastasis is a very rare entity. Long-term survival can be achieved after surgical resection and should be considered for all patients.

Pyoderma gangrenosum: a misdiagnosis.

Pyoderma gangrenosum is an inflammatory disease of unknown etiology, commonly mistaken for an infection. Here, we report the case of a 55-year-old woman with an infectious process that was initially misdiagnosed as pyoderma gangrenosum and treated accordingly. We also discuss the criteria and the methods available to diagnose infections and pyoderma gangrenosum correctly.

A review of Parry-Romberg syndrome.

Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare disorder characterized by unilateral facial atrophy affecting the skin, subcutaneous tissue, muscles, and sometimes extending to the osteocartilaginous structures. It has been associated with various systemic manifestations, particularly neurologic, ophthalmologic and maxillofacial. In this article, we review Parry-Romberg syndrome with its associated findings (neurologic, ophthalmologic, cardiac, rheumatologic, endocrinologic, infectious, orthodontic and maxillofacial, and autoimmune), underlying cause, differential diagnoses (en coup de sabre, scleroderma, and Rasmussen encephalitis), and therapeutic options.
