What condition often occurs in patients with both psoriasis and a fissured tongue?

Migratory glossitis, sometimes referred to as geographic tongue, is a condition characterized by irregular, smooth red patches on the dorsal surface of the tongue. These patches can change in size and shape over time and are often surrounded by a white or yellow border. In the context of psoriasis, individuals may exhibit both skin lesions and oral manifestations, with migratory glossitis frequently occurring alongside a fissured tongue.

Fissured tongue is a benign condition where grooves and fissures develop on the tongue's surface. Patients with psoriasis, an autoimmune disorder that primarily affects the skin, are more prone to developing oral conditions such as migratory glossitis due to their immune system's altered response.

In this situation, while conditions like oral lichen planus, geographic tongue, or oral candidiasis can manifest in the oral cavity, migratory glossitis is specifically noted for its sporadic, map-like appearance, which can be commonly seen in individuals who already have a predisposition to psoriasis. Migratory glossitis shares a direct relationship with the inflammatory nature of psoriasis, making it the most relevant choice in conjunction with a fissured tongue.
