Infantile myofibromatosis (IM) is the most common fibrous disorder of infancy and early childhood. Solitary intracranial involvement is rare and often unrecognized. This makes its early diagnosis and adequate management difficult. The majority of lesions are localized to the skull or dura with variable intracranial extension. Herein, we report a misdiagnosed and aggressive presentation of a solitary IM of the petrous bone. Our aim is to discuss histopathological differential diagnoses and management difficulties.

Xanthogranulomatous prostatitis is a rare benign inflammatory process of the prostate. Only few cases have been reported in the English literature. Xanthogranulomatous prostatitis is usually an incidental finding after needle biopsy or transurethral resection of the prostate in patients suffering from low urinary tract symptoms. We report the case of a 59-years-old patient diagnosed with prostatic abscess managed by transurethral resection of the prostate. Histopathological examination of resected prostatic tissue revealed abscessed xanthogranulomatous prostatitis with no evidence of malignancy. Xanthogranulomatous prostatitis presenting as a prostatic abscess is a rare finding. To the best of our knowledge our case represents the fourth case of xanthogranulomatous prostatitis presenting as prostatic abscess reported in the English literature so far.
