Dermatological complications due to post‑COVID‑19 syndrome: A systematic review.

Almost 20% of patients affected by COVID-19 develop dermatological symptoms after recovery. This condition is termed as post-COVID-19 syndrome and is characterized by a state of hyperinflammation, as well as deregulations in the humoral response of CD8 T-cells. Since there is no specific treatment for these injuries, the treatment of choice depends on the symptoms; thus, it is essential to provide a description of the type and nature of the injuries presented.

[Marjolin's ulcer associated with verrucous carcinoma in an immunocompromised patient].

Background: Marjolin's ulcer is the malignant degeneration of any chronic wound, with a latency period from tissue injury to variable malignant transformation that may occur up to 30 years later. Among the associated neoplasms, squamous cell carcinoma (SCC) is the predominant lineage in up to 71% of cases. The verrucous carcinoma variant has been estimated to have a low presentation, being described in the literature as 2% of all SCC and reported anecdotally in immunosuppressed patients, which justifies the objective of this publication.
