Intertrigo is a common inflammatory dermatosis of opposing skin surfaces that can be caused by a variety of infectious agents, most notably candida, under the effect of mechanical and environmental factors. Symptoms such as pain and itching significantly decrease quality of life, leading to high morbidity. A multitude of predisposing factors, particularly obesity, diabetes mellitus, and immunosuppressive conditions facilitate both the occurrence and recurrence of the disease. The diagnosis of candidal intertrigo is usually based on clinical appearance. However, a range of laboratory studies from simple tests to advanced methods can be carried out to confirm the diagnosis. Such tests are especially useful in treatment-resistant or recurrent cases for establishing a differential diagnosis. The first and key step of management is identification and correction of predisposing factors. Patients should be encouraged to lose weight, followed up properly after endocrinologic treatment and intestinal colonization or periorificial infections should be medically managed, especially in recurrent and resistant cases. Medical treatment of candidal intertrigo usually requires topical administration of nystatin and azole group antifungals. In this context, it is also possible to use magistral remedies safely and effectively. In case of predisposing immunosuppressive conditions or generalized infections, novel systemic agents with higher potency may be required.

Granular parakeratosis (GP) is a rare, idiopathic, and benign skin condition that presents classically as erythematous to brown hyperkeratotic papules that can coalesce into plaques. Axillary GP was initially observed by Northcutt and colleagues and has since been described in various other areas of the body including other intertriginous and non-intertriginous sites. The term "granular parakeratosis" is now used to describe not only the skin condition, but also a distinctive histological reactive pattern on biopsy specimens that are either regarded as the disease itself, or merely as an incidental finding. Upon review of the current findings, opinions, and associations of this entity, we propose the reappraisal of GP as a reactive pattern, rather than a distinct entity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
