Cutaneous mucinosis is an idiopathic condition characterized by an excessive accumulation or deposition of dermal mucin. It is rare in dogs, except for Chinese Shar Pei dogs. It appears as mild, moderate, or severe exaggeration of skin folds, especially on the head, ventrum, and distal extremities.
Cutaneous mucinosis What is. ?: In this condition there is a build-up of abnormal amounts of mucin (thick, clear, sticky fluid) under the skin. It occurs primarily in the Chinese shar pei which has more skin mucin than other breeds to begin with.The abnormal deposition of mucin may be the primary etiology of a cutaneous mucinosis, as in the case of CMI. In addition, abnormal extracellular mucin accumulation can be the result of a secondary disease process in the context of a systemic condition.Primary cutaneous mucinoses are a heterogeneous group of diseases characterized by the abnormal deposition of glycosaminoglycans (mucin) in the skin. This is the main histopathological clue resulting in distinctive clinical presentations.
The clinical validity of this classification has been validated by several large studies, including follow-up data of more than 1300 patients with a primary cutaneous lymphoma. 2,4,5 Although there was consensus between the EORTC and WHO classifications on the classification of most types of CTCLs, remaining differences between the 2 classification systems, in particular the controversy on the.
In both the EORTC (European Organization for Research on the Treatment of Cancer) 1 classification for primary cutaneous lymphomas and in the WHO (World Health Organization) classification, 3 only pagetoid reticulosis and MF-associated follicular mucinosis have been categorized as separate entities. Hereinafter, the latter condition will be referred to as follicular MF, a term also used in the.
Abstract Lichen myxedematosus (LM) is an idiopathic cutaneous mucinosis; its classification dates back to 1953, when Montgomery and Underwood distinguished 4 types of LM.
Cutaneous mucinosis can also be classified as localized or diffuse, and includes conditions such as papular mucinosis (lichen myxedematosus), foUicular mucinosis, focal cutaneous mucinosis, and cutaneous mucinosis of itrfancy. Deposition of mucin is a prominent histologic feature in generalized and localized myxedema seen in thyroid disease.
This article deals with the clinical and histopathologic features and the treatment of the distinctive cutaneous mucinoses and updates their classification. They may be divided, according to the microscopic location of mucin, into dermal and follicular mucinoses. The former group includes: lichen myxedematosus, acral persistent papular mucinosis, reticular erythematous mucinosis, scleredema.
Cutaneous leishmaniasis is a localised reaction at the inoculation site, which tends to be uncovered areas such as the face, hands and lower legs. Between 2 weeks and 2 months after the sand fly’s bite, a red papule forms. The area begins to swell and become irritated and after 3-4 weeks, flat ulcers form which eventually harden and form crusted margins. The volcano-like lesions that form.
Classification of Cutaneous Mucinosis. Cutaneous Mucinoses are classified into two main categories and then those two categories are further divided into various parts. The two main categories of Cutaneous Mucinosis are written below along with subcategories: A. Localized Mucinoses. The Localised Mucinoses is further divided into six different types i.e. Angiomyxoma; Mucinous Nevus; Papular.
The clinical aspects and the histologic features of cutaneous mucinoses have been reviewed and their classification updated. Cutaneous mucinoses are divided into distinctive (primary) cutaneous mucinoses in which the mucin deposit is the main histologic feature resulting in clinically distinctive lesions, and disorders associated with histologic mucin deposition as an additional finding.
It is of significance that cutaneous conditions that are known to be associated with HIV infection, like cutaneous mucinosis, draw attention to a possible HIV infection (10). In the case of papular mucinosis, there is no definite relation to syphilis alone and due to the concomittant treatment in the case of our patient, resolution of skin symptoms cannot be bound exclusively to the use of.
Secondary cutaneous mucinosis with systemic lupus erythematosus. A case presentation and review of the literature. Gammon WR, Caro I, Long JC, Wheeler CE Jr. Arch Dermatol, (3):432-435 MED: 415667 Multiple cutaneous focal mucinoses with hypothyroidism. Jakubovic HR, Salama SS, Rosenthal D. Ann. Intern. Med., (1):56-58 MED: 7053704 Cutaneous mucinosis associated with thyroid dysfunction.
Cutaneous features were classified according to the Gilliam and Sontheimer classification of cutaneous lupus. Results: Most (81.5%) patients were black African females. The mean (SD) age at.
Memenin noduler musinozu (NM), genellikle meme basi ve areolar bolgeyi etkileyen, nadir gorulen bir hastaliktir. Siklikla kadinlarda, yavas buyume seyri gosteren, asemptomatik, deri alti kitleler halinde ortaya cikar. Burada, sol meme basinda deri alti kitle ile basvuran 43 yasinda bir erkek hasta sunulmaktadir. Histopatolojik degerlendirme sonucunda memenin NM tanisi dogrulanmistir.
The classification system used to grade mast cell tumors in dogs is unreliable in horses because of the variable histologic appearance of tumors in this species. Alopecia and ulceration are variable features. A variant of cutaneous mast cell tumor is seen in newborn foals, in which the lesions may become generalized but regress over time, suggesting an equine equivalent of urticaria pigmentosa.
An updated classification of idiopathic cutaneous mucinosis (lichen myxoedematosus), included three clinicopathological subsets: a generalized papular and sclerodermoid form, a localized papular form, and an atypical or intermediate form. Cutaneous mucinosis occurring in infancy is very rare. We report a 7-month-old boy with a history of multiple opalescent papules over his fingers and toes.
