Dermatomyositis (DM) can be a rapidly fatal disease, as illustrated by a case of cutaneous lymphangitis carcinomatosa. This rare paraneoplastic syndrome highlights the aggressive potential of DM.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Dermatomyositis (DM) is an idiopathic inflammatory myopathy.
- Paraneoplastic syndromes can manifest with various cutaneous findings.
- Cutaneous lymphangitis carcinomatosa is a rare manifestation of metastatic adenocarcinoma.
Observation:
- A 70-year-old woman with newly diagnosed DM presented with painful, erythematous plaques and nodules.
- A skin biopsy revealed cutaneous lymphangitis carcinomatosa, suggesting an underlying malignancy.
- Extensive workup failed to identify the primary tumor site.
Findings:
- The patient received palliative chemotherapy but experienced disease progression.
- The patient died 6 months after initial presentation.
- This case represents a potential novel association between DM and cutaneous lymphangitis carcinomatosa.
Implications:
- This case highlights the potential for DM to be a rapidly lethal condition.
- The association between DM and cutaneous lymphangitis carcinomatosa warrants further investigation.
- Early recognition and management of paraneoplastic syndromes in DM are crucial.
