Clinicopathological diagnosis of morphea-like carcinoma en cuirasse in the neck: a rare presentation of lung cancer.

BACKGROUND

Carcinoma en cuirasse is mostly reported in breast cancer. It rarely originates from other visceral tumors such as lung cancer. In this report, we highlight the importance of skin biopsy not to make a misdiagnosis or missed diagnosis.

CASE PRESENTATION: We report a 51-year-old male, diagnosed with lung adenocarcinoma 2 years ago, presenting as swelling and hardening of the face and neck. The patient was diagnosed with carcinoma en cuirasse from lung cancer and was transferred to the oncology department for further management. Unfortunately, the patient gave up treatment after 3 months and died after 1 year of follow-up.

CONCLUSION

In patients with tumors that present as swelling and hardening of the skin, the possibility of skin metastases should be considered, and the necessity of early skin biopsy should be taken into account.
