| Type | Causative Agent / Mechanism | Key Features |
|---|---|---|
| Candidal (most common) | Candida albicans | Satellite lesions, white discharge, associated with diabetes/immunosuppression |
| Bacterial | S. aureus, Streptococcus spp. (A, B, D), anaerobes | Purulent discharge, cellulitis |
| Aerobic/Mixed | Polymicrobial | Subpreputial discharge, malodor |
| Circinate balanitis | Reactive arthritis (formerly Reiter's syndrome) | Painless, superficial erosions; associated with urethritis, arthritis, uveitis |
| Plasma cell (Zoon's) | Idiopathic, chronic | Moist, well-demarcated, orange-red patches on glans; older uncircumcised men |
| Lichen sclerosus (BXO) | Autoimmune | White, sclerotic plaques; risk of meatal stenosis and phimosis |
| Lichen planus | Autoimmune | Purple polygonal papules/erosions |
| Psoriatic | Psoriasis | Well-defined erythematous plaques; may lack silvery scale on glans |
| Fixed drug eruption | Drug hypersensitivity (NSAIDs, tetracyclines, sulfonamides) | Recurrent, same site with drug re-exposure |
| Contact/irritant | Soaps, spermicides, latex, antiseptics | History of exposure, resolves on removal |
| Premalignant/Malignant | Erythroplasia of Queyrat, Bowen's disease, SCC | Persistent red velvety plaque; biopsy mandatory |
| Type | Treatment |
|---|---|
| Candidal | Topical clotrimazole 1% cream BD for 7–14 days; sexual partner treatment if symptomatic (STI Guidelines, p. 95) |
| Bacterial | Topical fusidic acid or oral flucloxacillin; metronidazole if anaerobes suspected |
| Mixed/non-specific | Saline soaks, topical antibacterial/antifungal combinations |
| Circinate (reactive) | Topical steroids; treat underlying condition |
| Zoon's plasmacellularis | Topical steroids; circumcision is curative |
| Lichen sclerosus (BXO) | Potent topical steroids (clobetasol propionate); circumcision often required |
| Psoriasis/Lichen planus | Mild-moderate topical corticosteroids |
| Contact/irritant | Remove irritant; mild topical steroid if needed |
| Fixed drug eruption | Identify and withdraw offending drug |

phimosis grading scale clinical features complications paraphimosis
circumcision surgical technique indications complications
| Grade | Description |
|---|---|
| 0 | Full retraction — no phimosis |
| 1 | Full retraction, tight behind glans |
| 2 | Partial exposure of glans |
| 3 | Partial retraction, meatus just visible |
| 4 | Slight retraction, but neither meatus nor glans visible |
| 5 | Absolutely no retraction |
| Procedure | Description | Indication |
|---|---|---|
| Circumcision | Complete removal of the prepuce | BXO, failed medical therapy, recurrent balanitis, patient/parent preference |
| Preputioplasty | Foreskin-preserving widening (dorsal slit ± closure) | Mild–moderate pathological phimosis; desire to preserve foreskin |
| Dorsal slit | Longitudinal incision of prepuce | Acute/emergency access; rarely used as definitive procedure |
| Complication | Notes |
|---|---|
| Paraphimosis | Retracted foreskin trapped behind glans — urological emergency; causes glans oedema and potential ischaemia |
| Urinary retention / obstructive uropathy | Severe phimosis with pin-hole meatus |
| Recurrent balanitis | Stagnant secretions under foreskin |
| Sexual dysfunction | Painful erections, inability to have intercourse |
| Penile carcinoma | Chronic inflammation (especially BXO) is a recognised risk factor |
