Key Clinical Message Neuroendocrine tumors of the bladder are rare, accounting for less than 1% of all bladder tumors. Among these, large cell neuroendocrine carcinoma is an extremely uncommon subtype. We report on a histologically confirmed case of mixed both large and small cells neuroendocrine tumor of the bladder in a 64‐year‐old male with a history of bilharzial cystitis. The diagnosis was made after radical cystectomy with Immunohistochemical staining revealing positivity for synaptophysin, CD56, and AE1/3. While bilharzia is commonly linked to squamous cell carcinoma in the bladder, the potential relationship with neuroendocrine tumors is still relatively unexplored in this context. This case marks the first reported instance of the atypical coexistence of bilharzial cystitis and mixed large and small cell neuroendocrine carcinoma of the bladder. This unique case of coexisting highlights a rare phenomenon warranting further study. Similar associations have been documented in other organs, emphasizing the importance of exploring underlying mechanisms and clinical implications for improved patient care and outcomes.

Key Clinical Message Penile self‐mutilation may result from a suicidal attempt during a major depression crisis. The management of this urological emergency should be multidisciplinary. A macroscopic penile reimplantation performed meticulously by a urological surgeon may yield an excellent cosmetic and functional outcome. Abstract Penile self‐mutilation is an infrequent form of self‐harming behavior seen primarily in patients with schizophrenia spectrum disorders and rarely reported in those with major depressive disorders. We herewith present a major depression related case of penile self‐mutilation successfully managed by macroscopic penile reimplantation performed 8 h after the incident.
