Background: Subcutaneous mycoses caused by opportunistic filamentous fungi are emerging infections in developed countries due to the longer survival of immunocompromised patients. The evidence published in relation to subcutaneous mycoses is fundamentally based on case reports and small case series.
Methods: We performed an observational retrospective study of subcutaneous mycoses caused by opportunistic filamentous fungi diagnosed at our institution between 2017 and 2022.
Background: Progressive nodular histiocytosis (PNH) is an extremely rare type of non-Langerhans cell histiocytosis, characterized by the emergence of hundreds small to large cutaneous papulonodules without spontaneous remission. It can be life-threatening if pharyngeal and laryngeal mucosa were involved, just as we reported in this case. Disfigurement and disabling are common, whereas current treatment options are of limited efficacy.

Background: Cutaneous and mucocutaneous histiocytosis (group C) comprise a wide variety of entities affecting skin and/or mucosae. Although they are considered as reactive proliferations, their exact pathophysiology remains unknown and, therefore, they lack a specific treatment.
Aims: The aim of this study is to review the evidence on cases of histiocytosis treated with UVB and/or UVA and to report a new case of relapsing group C histiocytosis that has been successfully treated with PUVA therapy.
