CERESETTO, José M. et al. Colonic pseudotumoral involvement as an expression of severe plasminogen deficiency. Medicina (B. Aires) [online]. 2023, vol.83, n.6, pp.1003-1006. ISSN 0025-7680.

Plasminogen deficiency is a very rare multisystem entity that affects different tissues of the economy through the de position of fibrin-rich pseudomembrane and determines a heterogeneous and diverse clinical presentation. It is trans mitted in an autosomal recessive manner by mutations of the PLG gene on chromosome 6 and can be divided into hypoplasminogenemia or type I and dysplasminogenemia or type II, the latter not related to clinical pathology. Severe plasminogen deficiency has a prevalence of 1.6 individuals per million inhabitants and although it can be diagnosed in adulthood, the most severe symptoms are observed in infants and children. The most common form of onset is the so-called woody conjunctivitis, characterized by fibrin membranes that are deposited on the eyelids since child hood, causing exophytic lesions that affect vision. It can also affect other mucous membranes such as the gingival, respiratory, oropharyngeal, digestive and genital mucosa, among others. We present a rare case of severe plasminogen deficiency with conjunctivitis and woody cervicitis who was admitted with clinical acute abdominal symptoms, associated with a tumor mass due to pseudomembranous deposition in the ascending colon that simulated inflam matory bowel disease and resolved spontaneously.
