- Squamous Cell Carcinoma Arising in Ungual Lichen Planus: Report and Review(2021) TAKATU, Caroline Maris; GABBI, Tatiana Villas Boas; NICO, Marcello Menta SimonsenBackground: Lichen planus (LP) can lead to severe scarring of the nail unit leading to anonychia. There are very few reports of squamous cell carcinoma (SCC) occurring in the lesions of ungual LP. Objective: The aim of this study was to revise the previously reported cases of SCC appearing in ungual LP and to present a new case. Methods: A PubMed search was performed with the terms ""nail lichen planus"" and ""squamous cell carcinoma."" Reported cases as well as a new case were depicted in a table. Results: Only 2 indexed articles reporting 3 cases were found. All patients suffered of long-lasting scarring ungual LP. Conclusions: The occurrence of SCC in nail LP is rare. LP is not ""premalignant"" per se, but SCC might rarely arise in LP scars.
- Porokeratosis of the Nail Unit: Case Series and Review(2021) YENDO, Tatiana Mina; GABBI, Tatiana Villas Boas; NICO, Marcello Menta SimonsenBackground: The lesions of porokeratosis (PK) lead to skin atrophy and scarring as long as they spread centrifugally. PK affecting the nail unit is seldom described. Objective: The aim was to revise the previously reported cases of ungual PK and to present 3 new cases. Methods: A PubMed search was performed with the keywords ""nail"" and ""porokeratosis."" Previously reported cases as well as 3 new cases are depicted in tables. Results: Only 11 cases of ungual PK were found; 3 new cases have been added. All patients presented with typical lesions of PK (Mibelli, isolated, segmental, or ostial eccrine types) that happened to affect nails due to nail matrix or nail bed compromise, resulting in mild to severe nail scarring, including irreversible anonychia. The present 3 case series contrast with the previous single case reports. Conclusions: PK affecting the nails is exceedingly rare. Changes in nails affected by PK are irreversible, since, as on the skin, this is a chronic scarring process.
