Although uncommon in children, a more generalized type of follicular mucinosis can present very similar to lichen spinulosus.
Lymphocytic infiltration of the skin (Jessner-Kanof) but not reticular erythematous mucinosis occasionally represents clinical manifestations of Borrelia-associated pseudolymphoma.
Cutaneous mucinosis encompasses a heterogeneous group of skin diseases characterized by the deposition of mucin in the interval of the dermis (2).
Other differential diagnoses include self-healing juvenile cutaneous mucinosis and acral persistent papular mucinosis.
SPAID, a spontaneously occurring auto-inflammatory disease, causes fever, swollen joints, cutaneous mucinosis (a skin disorder), ear problems, and kidney failure.
Interestingly, in a case of self-healing papular mucinosis, which is a milder form of sclerodermoid lichen myxedematosus, CD34+ or FXIII-A-positive DCs have been described next to mast cells, suggesting that these cells together could contribute to the dermal mucin deposition of the lesions [67].
Other drugs that have been associated with PCA are hepatitis B vaccines causing Graham-Little-Piccardi-Lasseur syndrome [33], anticonvulsants and cyclosporine causing acne keloidalis nuchae (AKN) [34-36], and imatinib causing follicular mucinosis [37].
(3) Histopathologically, in addition to folliculotropism, features such as epidermotropism, syringotropism, follicular mucinosis, and granulomatous inflammation can be seen as per the spectrum of atypical cutaneous lesions.
For example, if there is no lichenoid inflammation present histologically, the diagnosis is not lichen planus; absence of granulomata excludes sarcoidosis; lack of dermal mucin rules out a mucinosis. When certain inflammatory cells are absent, this should also be mentioned when relevant.
The painless, 3.0-cm tumor was initially mistaken for reticular erythematous mucinosis, a benign skin condition that occurs when fibroblasts produce abnormally large amounts of mucopolysaccharides.
