Incidental detection of renal cell carcinoma during routine screening in a patient with schizophrenia: a case report

Introduction

Schizophrenia and other severe mental illnesses (SMI) are associated with significantly increased physical morbidity and premature mortality, largely attributable to preventable or treatable medical conditions [1,2]. Diagnostic overshadowing, reduced help-seeking behaviour, stigma, and fragmented healthcare systems contribute to delayed somatic diagnoses in this population [2,3]. In oncology, individuals with SMI are less likely to participate in cancer screening programmes and may experience delays across the entire care pathway, from early detection to treatment [4,5].

Aims

To present a case illustrating that timely detection of serious somatic illness in patients with schizophrenia is achievable when routine physical health assessment is systematically integrated into psychiatric inpatient care.

Case Presentation

A man in his late 40s with a 15-year history of schizophrenia was admitted for acute psychotic exacerbation. He had been adherent to oral paliperidone 9 mg/day during a four-year remission period. On admission, he presented with paranoid-persecutory delusions focused on hospitals and medical procedures, which had previously prevented him from seeking healthcare. Routine inpatient urinalysis revealed persistent microscopic haematuria (+1 erythrocytes on repeated samples). Renal function was within normal limits, and the patient denied gross haematuria, flank pain, or systemic symptoms. He reported overflow-type urinary incontinence but did not consider it clinically relevant. Abdominal ultrasonography unexpectedly demonstrated a suspicious renal mass; subsequent contrast-enhanced computed tomography confirmed a lesion radiologically consistent with renal cell carcinoma (RCC). Urology consultation recommended prompt surgical intervention. Following disclosure of the diagnosis, the patient was reluctant to accept surgery, driven by paranoid beliefs about medical procedures and limited illness awareness, raising questions regarding decision-making capacity.

Results

The diagnosis was established solely because routine urinalysis findings were taken seriously and systematically pursued. The absence of classic symptoms and normal renal function tests highlight how readily this malignancy could have remained undetected. This case further illustrates that active psychosis may substantially impair treatment acceptance, necessitating formal capacity assessment and close multidisciplinary collaboration between psychiatry and urology.

Conclusions

This case demonstrates that individuals with schizophrenia are at risk not only for delayed diagnosis of physical illness but also for difficulties in accessing and accepting appropriate medical treatment [1,2]. At the same time, it conveys a clear message: the timely detection of serious somatic diseases is achievable when routine physical health assessments are integrated into psychiatric care [2]. The incidental detection of renal cell carcinoma in this patient highlights the life-saving potential of standardized medical screening in psychiatric settings. Such findings also underscore the value of low-cost, repeatable bedside investigations as gateways to earlier referral, shared decision-making, and potentially curative treatment within psychiatric hospitals overall. Embedding physical health monitoring into routine psychiatric practice should be regarded as a core clinical and ethical responsibility [2]. In such cases, balancing respect for patient autonomy with the duty to prevent serious harm is a key ethical challenge.
