Follicular mucinosis is a condition characterized by the abnormal accumulation of acidic mucopolysaccharides in hair follicles. It is classically described as occurring idiopathically in young persons and within the infiltrates of mycosis fungoides in older individuals. We report a 12-year-old girl who had erythrodermic follicular mucinosis, hypereosinophilia, circulating Sezary cells, and both...

RATIONAL Nodular cutaneous lupus mucinosis is regarded as a distinctive cutaneous mucinosis deposition with systemic lupus erythematosus(SLE). All typical cases occurred as asymptomatic cutaneous papules, nodules, or plaques on the trunk, upper and lower extremities, and face. Histopathology is mainly revealed abundant mucin deposits among splayed collagen bundles in the dermis. At the same tim...

BACKGROUND Self-healing juvenile cutaneous mucinosis is a rare disease affecting young people characterized by transient cutaneous lesions and sometimes mild inflammatory symptoms. The deep dermal and subcutaneous features of this disorder have not yet been well described. OBJECTIVE The purpose of our study was to present 3 cases of self-healing juvenile cutaneous mucinosis in which the histo...

Skin mucinosis is a rare skin disease which clinically manifests as firm papules and waxy nodules. We report a case of a 66-year-old female psoriatic patient who developed skin mucinosis during biological therapy. Because of a previous lack of response to the local and conventional systemic treatment of psoriasis, the patient received biological therapy (infliximab from June 2008 to May 2009 - ...

Follicular mucinosis is recognized as one of the histopathological reaction patterns characterized by the accumulation of mucin within follicular epithelium. It is induced by various causes including inflammatory diseases, and more than half of the cases are associated with malignant lymphoma, mainly mycosis fungoides. Herein, we describe the third documented case of adult T-cell leukemia/lymph...

Oral focal mucinosis is an uncommon non-neoplastic lesion of unknown etiology. We presented a unique case of a sessile, well-demarcated gingival nodule adjacent to the right mandibular first molar of a young girl submitted to orthodontic treatment that was diagnosed as oral focal mucinosis. The probably etiopathogenesis of this lesion in orthodontic patient is discussed.

Oral focal mucinosis is a rare clinicopathological entity that represents the mucosal counterpart of cutaneous focal mucinosis or cutaneous myxoid cyst. The aetiology is unknown. Oral focal mucinosis is most common in young adults. The gingiva is the most common site and the hard palate is the second most common location. A 19-year-old male patient presented with a 2 cm painless mass localized ...

Lichen myxedematosus is a cutaneous mucinosis of idiopathic origin. According to Rongioletti’s classification, 2006, lichen myxedematosus is classified into three forms. The scleromyxedema or lichen myxedematosus sclerodermiform and generalized is a form of lichen myxedematosus characterized by numerous papules and areas of cutaneous hardening due to the deposition of mucin in association with ...

Self-healing juvenile cutaneous mucinosis is an extremely uncommon disorder characterized by the acute eruption of multiple papules and subcutaneous nodules. In this report, we describe one of the youngest patients reported to date with self-healing juvenile cutaneous mucinosis and further define several of the histologic and clinical characteristics unique to the disorder. Awareness of this di...
