Differential Diagnosis for Whitish Smegma behind Foreskin and under/along Glans Corona
- Single most likely diagnosis
- Smegma: This is the most likely diagnosis due to the description of whitish material behind the foreskin and under/along the glans corona, which is a common location for smegma accumulation. Smegma is a natural, cheesy substance produced by the genital glands.
- Other Likely diagnoses
- Balanitis: Inflammation of the glans penis, which can cause a whitish discharge and may be associated with poor hygiene, leading to smegma accumulation.
- Candidiasis (yeast infection): Can cause a white, cheesy discharge and may be found under the foreskin or on the glans penis.
- Seborrheic dermatitis: A skin condition that can cause a white, flaky substance to form on the penis, including under the foreskin and on the glans.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Squamous cell carcinoma: Although rare, this type of cancer can present with a white, cheesy discharge and should not be missed due to its potential severity.
- Gangrene: In rare cases, poor hygiene and smegma accumulation can lead to gangrene, which is a life-threatening condition.
- Rare diagnoses
- Lichen sclerosis: A rare skin condition that can cause white, patchy lesions on the penis, including under the foreskin and on the glans.
- Leukoplakia: A rare condition characterized by white patches on the mucous membranes, including the glans penis.
- Vitiligo: A rare skin condition that can cause white patches on the penis, although it is not typically associated with a cheesy discharge.
