Penile Ulcer: Or something else? Differential Diagnosis

Skin and Subcutaneous (L00-L99).

  • Fixed drug exanthema (gets its name because the exanthema (rash) does not completely disappear after discontinuation of the “triggering” drug).
  • Furuncle – purulent inflammation of hair follicles or sebaceous glands.
  • Infected epidermal cyst – cysts originating from hair follicles, several millimeters to two centimeters in size, prallelastic, skin-colored, which can grow slowly and become infected
  • Lichen sclerosus (LS) (et atrophicus) (synonyms: lichen albus; lichen atrophicus; lichen sclerosus; lichen sclerosus et atrophicans; lichen sclerosus et atrophicus; morphoeid scleroderma; white spot disease; white spot diseas) – rare, chronic disease of the connective tissue, which is probably one of the autoimmune diseases.
  • Lichen ruber planus (nodular lichen).

Infectious and parasitic diseases (A00-B99).

Musculoskeletal system and connective tissue (M00-M99).

  • Behçet’s disease (synonym: Adamantiades-Behçet’s disease; Behçet’s disease; Behçet’s aphthae) – multisystem disease of the rheumatic type associated with recurrent, chronic vasculitis (vascular inflammation) of the small and large arteries and mucosal inflammation; The triad (the occurrence of three symptoms) of aphthae (painful, erosive mucosal lesions) in the mouth and aphthous genital ulcers (ulcers in the genital region), as well as uveitis (inflammation of the middle eye skin, which consists of the choroid (choroid), the ray body (corpus ciliare) and the iris) is stated as typical for the disease; a defect in cellular immunity is suspected

Neoplasms – tumor diseases (C00-D48).

  • Penile carcinoma (penile cancer)

Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99).

  • Balanitis (acorn inflammation), mycotic (“fungal”) or bacterial.
  • Balanitis circinata – in the setting of Reiter’s disease (synonyms: Reiter’s syndrome; Reiter’s disease; arthritis dysenterica; polyarthritis enterica; postenteritic arthritis; posturethritic arthritis; undifferentiated oligoarthritis; urethro-oculo-synovial syndrome; Fiessinger-Leroy syndrome; Engl. Sexually acquired reactive arthritis (SARA)) occurring acorn inflammation; Reiter’s triad: acute arthritis (joint inflammation), conjunctivitis (conjunctivitis), and urethritis (urethritis).
  • Balanitis xerotica et obliterans – acorn inflammation associated with atrophy and sclerosis (hardening) of the urethra.

Injuries, poisonings and other consequences of external causes (S00-T98).

  • Allergic contact dermatitis
  • Bites, unspecified
  • Injuries of the penis, unspecified (e.g., zipper injuries, frenulum tearing).
  • Self-mutilation, unspecified.
