Differential Diagnosis for Firm Skin on Chin
- Single most likely diagnosis
- Scleroderma: This is a condition characterized by the deposition of collagen, leading to thickening and hardening of the skin. The chin is a common area affected, and the firmness of the skin can be a presenting symptom.
- Other Likely diagnoses
- Keloid or Hypertrophic Scarring: These types of scars can cause firm, raised skin, especially if the chin has been previously injured or undergone surgery.
- Acne: Certain types of acne, such as nodulocystic acne, can cause firm, inflamed lesions on the chin.
- Contact Dermatitis: Irritation from contact with certain substances can lead to firm, thickened skin on the chin.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Basal Cell Carcinoma or Squamous Cell Carcinoma: Although less common, skin cancers can present as firm, non-healing lesions on the chin. Early detection is crucial for effective treatment.
- Sarcoidosis: This systemic disease can cause skin lesions, including firm plaques on the chin, and requires prompt diagnosis to manage systemic complications.
- Rare diagnoses
- Lipodermatosclerosis: A rare condition characterized by inflammation and scarring of the skin and subcutaneous fat, which can cause firm skin on the chin.
- Necrobiosis Lipoidica: A rare skin condition that can cause firm, yellowish-brown plaques, often on the lower legs but potentially on the chin.
- Granuloma Faciale: A rare, chronic condition that causes firm, reddish-brown plaques on the face, including the chin.
