Ainhum (dactylolysis spontanea): a case with hands and feet involvement

Area of Science:

• Dermatology
• Rare Diseases
• Genetics

Background:

• Dactylolysis spontanea (DS) is a rare condition characterized by spontaneous constriction and lysis of digits.
• Its etiology remains largely unknown, with most cases affecting the fifth toe.

Observation:

• The presented case involves dactylolysis spontanea affecting not only the toes but also the fingers.
• This presentation is highly unusual, as DS typically remains restricted to the digits without systemic involvement.

Findings:

• The disease manifests as a localized constriction, primarily impacting the distal phalanx.
• While commonly affecting the fifth toe, DS can involve other toes and, rarely, fingers.

Implications:

• This case expands the known clinical spectrum of dactylolysis spontanea.
• Further investigation into the etiology and genetic factors of DS is warranted.
• Understanding rare digit abnormalities is crucial for accurate diagnosis and management.
