Linear indurated plaque over the neck.

Area of Science:

• Dermatology
• Pathology

Background:

• Cutaneous swelling has diverse causes, often requiring pathological examination for accurate diagnosis.
• Morphea is a rare connective tissue disease characterized by localized skin hardening and thickening.

Observation:

• An 18-year-old male presented with a 6-month history of an asymptomatic, firm, linear lesion on his neck.
• The lesion's appearance raised suspicion for neoplastic conditions.

Findings:

• Histopathological examination was crucial for diagnosing the condition.
• The findings were consistent with morphea, specifically a linear keloidal subtype.

Implications:

• This case underscores the importance of histopathology in diagnosing unusual skin conditions.
• Recognizing uncommon presentations of morphea can prevent misdiagnosis of neoplastic diseases.
