A rare cutaneous pseudolymphoma case in a French adolescent presented as a nasal nodule. Histological analysis revealed lymphocyte infiltration of the hair follicle, with spontaneous resolution after biopsy.

Area of Science:

Dermatology
Pathology
Oncology

Background:

Reports a rare case of cutaneous pseudolymphoma.
Highlights the entity described in Japanese literature in 1999.
Discusses the debated individualization of this specific pseudolymphoma variant.

Observation:

A 13-year-old Caucasian French boy presented with a unique nasal papulonodule.
Histological examination showed dense, perifollicular lymphocyte infiltration penetrating the hair.
The lesion resolved spontaneously within two weeks after a partial biopsy.

Findings:

The case aligns with a previously described rare cutaneous pseudolymphoma.
Histological features include dense peripilary infiltrate disrupting the hair follicle.

Spontaneous resolution post-biopsy is a common outcome for non-surgically treated cases.

Implications:

Suggests that hair follicle involvement by facial pseudolymphomas is common and nonspecific.
Emphasizes the importance of histological examination for diagnosis.
Contributes to understanding rare dermatological conditions and their management.
