TLDR The report suggests that hair loss in Cronkhite-Canada syndrome may be caused by alopecia areata incognita, as shown by a patient's improvement with treatment.
The case report described a 49-year-old Chinese woman with Cronkhite-Canada syndrome who experienced rapid and extensive hair loss, gastrointestinal symptoms, and nail changes. A scalp biopsy indicated a possible mechanism of hair loss as alopecia areata incognita, characterized by a 'shift out of anagen' and increased telogen hair follicles with peri-bulbar lymphoid cell infiltrate. Treatment with prednisolone and mesalazine resulted in symptom improvement and hair and nail regrowth. This study suggested alopecia areata incognita as a potential cause of hair loss in Cronkhite-Canada syndrome, evidenced by the patient's response to treatment and biopsy results.
