A serpentine inside eccrine spiradenoma: a new trichoscopic sign

Area of Science:

• Dermatology
• Oncology
• Medical Imaging

Background:

• Eccrine spiradenoma is a rare benign adnexal tumor originating from sweat glands.
• Accurate diagnosis is crucial for appropriate management and to differentiate from malignant lesions.
• Trichoscopy offers non-invasive in vivo visualization of scalp structures.

Observation:

• A case of a female patient presenting with an erythematous scalp tumor was investigated.
• Histopathological examination confirmed the diagnosis of eccrine spiradenoma.
• Trichoscopic evaluation of the lesion was performed to identify characteristic features.

Findings:

• Trichoscopy demonstrated a distinctive pattern in eccrine spiradenoma characterized by linear, serpentine red structures.
• This 'serpentine' pattern was identified as a potential hallmark feature of the tumor.
• The study highlights the utility of trichoscopy in visualizing specific vascular patterns within skin tumors.

Implications:

• The identified trichoscopic pattern may serve as a valuable diagnostic aid for eccrine spiradenoma.
• This non-invasive technique could potentially reduce the need for biopsies in certain cases.
• Further research validating this trichoscopic hallmark could enhance early and accurate diagnosis of eccrine spiradenoma.
