Axillary Granular Parakeratosis

Background:

Granular parakeratosis is a hyperkeratotic eruption of unknown etiology that occurs in the axilla and other intertriginous areas. The histologic features are unique for the retention of keratohyalin granules in the stratum corneum.

Objective:

The aim of the article is to review the clinical manifestations and treatment of granular parakeratosis.

Methods:

A case report and literature review are presented.

Results:

Twenty-six cases of granular parakeratosis now have been reported and reviewed.

Conclusion:

Granular parakeratosis occurs predominantly in middle age women and most frequently in the axilla. A number of treatments have been applied to the 26 cases reported to date, without consistent responses. No evidence-based therapy can be suggested at present.

Adult acral cutaneous myofibromas in a patient with generalized morphea

Myofibroma is the term for a group of solitary or generalized soft tissue tumors that may be located in the skin or within skeletal muscle, bone, and viscera. These tumors occur most commonly in children. However, examples of myofibroma have been reported in adults, in whom they usually present as solitary lesions of the head and neck, trunk, and extremities. "Cutaneous nodules" have been reported in both localized and systemic scleroderma, but to our knowledge, there are no specific reports of myofibromas developing in this patient population. We report a case of acral myofibromas in a patient with generalized cutaneous morphea. This occurrence is of interest in view of the possible role of myofibroblasts in the pathogenesis of scleroderma.
