An Incidental Finding Of A Tumour In A Case Of Pityriasis Rubra Pilaris- A Case Report

We report a 49-year-old man who had a progressive rash that covered 90% of his total surface area in a period of 5 years. Confluent scaly erythematous plaques, which started on the upper back and spread to involve the scalp, face, chest, and limbs. Notable observations were subungual hyperkeratosis and onychogryphosis in all nails, along with follicular keratotic papules with waxy keratoderma on the palms and soles. Biopsy from skin lesions were suggestive of PRP. A focal hypoechoic thickening at the base of the bladder was found during abdominal ultrasonography, which could indicate edema or a tumor. Histopathological examination of the removed tissue following TURBT revealed cystic urothelial nests that were consistent with Cystitis Cystica Glandularis (CCG), ruling out cancer. This case underscores the importance of a thorough investigation in patients with extensive dermatoses, highlighting a rare association between PRP and cystic bladder lesions
