Periodontitis may be associated with psoriasis but further studies are required to elucidate their relationship in the context of the biologic plausibility.
Solitary trichoepithelioma (TE) is a rare, benign tumor of follicular origin that in certain cases is difficult to differentiate from basal cell carcinoma (BCC). We report the case of an 8-year-old girl with a pale pink, soft lesion on the neck. The clinical image of the lesion was equivocal, while some dermoscopic findings—blue-gray globules and arborizing vessels—could not exclude the presence of BCC from the differential diagnosis, although that would have been a very unlikely case considering the age of the patient. The histopathologic examination established the diagnosis of TE. Given the occasion of this challenging case we try to list the key clinical, dermoscopic and histopathological characteristics of TE and BCC in order to elucidate the differential diagnosis of these two entities.
Literature data regarding the impact of pandemic on psoriasis and the relationship between psoriasis and COVID-19 outcomes are emerging. [1][2][3][4][5][6][7][8] The main aim of this study was to evaluate the impact of COVID-19 on treatment maintenance, disease course, psychosocial status, and intention to vaccinate in patients with moderate to severe psoriasis under systemic treatment (biologic agents, conventional systemic
Under the umbrella of cutaneous sarcomas (CS) we include a heterogeneous group of rare, malignant, mesenchymal neoplasia, such as dermatofibrosarcoma protuberans, atypical fibroxanthoma, cutaneous undifferentiated pleomorphic sarcoma, cutaneous angiosarcoma and leiomyosarcoma. Clinical presentation and histopathological examination are the cornerstone of CS diagnosis and classification. There are scarce data in the literature in regards to the clinical and dermatoscopic characteristics of CS and the role of dermatoscopy in their early identification. We performed a literature review, aiming to summarize current data on the clinical and dermatoscopic presentation of the most common types of cutaneous sarcomas that may facilitate early diagnosis and prompt management. Based on the available published data, CS are characterized by mostly unspecific dermatoscopic patterns. Dermatofibrosarcoma protuberans, Kaposi’s sarcoma, and in a lesser degree, cutaneous angiosarcoma, may display distinct dermatoscopic features, facilitating their early clinical recognition. In conclusion, dermatoscopy, in conjunction with the overall clinical context, may aid towards suspicion of CS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
