A case of a deeply fissured tongue

Cerebriform Tongue

Cerebriform tongue (CT) is diagnosed to be a benign clinical condition that is characterized by grooves on the dorsal surface of the tongue and referred with other terminologies such as the scrotal tongue, grooved tongue, lingua fissurata, and lingua plicata which can be chronic trauma, vitamin deficiencies, and probably not a developmental malformation. The incidence of this condition was predominant among males and found to be higher with increasing age. It is very rarely observed in children. It is usually painless and sometimes food debris accumulation can irritate. CT has been reported with the association of various systemic factors and syndromes. A case of a 62-year-old male with CT is presented along with the review of the literature.

Unraveling oral psoriasis and its relationship with geographic tongue: A literature review

Differentiating between oral psoriasis and geographic tongue is difficult and controversial because some patients with geographic tongue do not necessarily have psoriasis. Furthermore, the number of clinical studies, reporting histopathological and genetic evidence for the definitive diagnosis of oral psoriasis, is limited. The aim of this literature review was to obtain data for supporting the diagnosis of oral psoriasis with particular emphasis on the relationship between psoriasis and geographic tongue. Based on the current data, it can be concluded that geographic tongue is the most common oral lesion in psoriasis, and histopathological, immunohistochemical, and genetic similarities have been observed between the two diseases. This review also emphasizes the importance of conducting oral examinations in patients with psoriasis and skin examinations in patients with geographic tongue.

In search of oral psoriasis

Even though psoriasis is a common skin disorder, reports of it involving the oral cavity are exceedingly rare, with less than 100 publications in the literature. Biopsy-proven oral psoriasis has been reported in the oral medical literature, but the commonest oral mucosal findings in most studies are associated non-specific features including fissured and geographic tongue. Case series on this entity have not provided any definitive data to support its existence. From the evidence available to date, it is still unclear if oral psoriasis is a distinct entity or if, indeed, it exists.
