Shave and Phenolization of Periungual Fibromas, Koenenʼs Tumors, in a Patient with Tuberous Sclerosis:

Symptomatic Periungual Fibroma of the Hand

Periungual fibromas are benign nodules commonly found on acral digital areas that are commonly associated with tuberous sclerosis. They vary in size and are challenging to treat, with a high recurrence rate. We present a case of a patient with a periungual fibroma, which by virtue of its size, was of functional concern. The intraoperative findings and their implications on the clinical outcome, together with a literature review on other treatment modalities, are also presented.

Cutaneous manifestations of tuberous sclerosis complex and the paediatrician's role

Tuberous sclerosis complex (TSC) is a multisystem genetic disorder stemming from unregulated activation of the mammalian target of rapamycin (mTOR) pathway, resulting in the growth of hamartomas in multiple organs. TSC-related skin lesions often develop early in life and can be disfiguring, emotionally distressful and even painful at times. Recognition of TSC-associated skin features by paediatricians can be a catalyst for facilitating early implementation of treatment strategies and establishing appropriate follow-up care. The range of potential treatment options for symptomatic or disfiguring TSC-associated skin lesions includes non-pharmacological (surgical excision, laser therapy) and pharmacological (eg, topical or systemic mTOR inhibitors) alternatives. In this review, we discuss the relevance of TSC-associated skin findings, highlight available treatment options, review guideline recommendations and emphasise the role of the primary care physician in the management of this complex disease.

Ungual fibroma in 12-year-old boy with hypomelanotic macules, intellectual disability and attention deficit hyperactivity disorder-possible tuberous sclerosis

Objective:

To report a case of a 12-year-old boy with intellectual disability and attention deficit hyperactivity disorder, who came to surgery for an examination due to a minor bulge on the left thumb, which had been growing for the previous month. His mother denied any trauma.

Methods:

After the removal of the clinically ambiguous bulge and a pathohistological confirmation that it was a periungual fibroma, complete patient analysis was performed due to the presence of hypomelanotic macules and a suspected tuberous sclerosis.

Results:

Considering the presence of hypomelanotic macules, as one of the main criteria, possible TS diagnosis was set.

Conclusion:

Early detection of the symptoms of TS enables a timely provision of protocols for further patient monitoring, which affects the patient’s morbidity and mortality.

Tuberous Sclerosis Complex: An Update for Dermatologists

Tuberous sclerosis complex is an autosomal dominant disorder that often manifests early in life with cutaneous features, and it is important that dermatologists who care for children remain up to date on its diagnosis and management. This article provides an update regarding the most recent guidelines for diagnosis published by the International Tuberous Sclerosis Complex Consensus Conference, which took place in 2012, and provides a brief literature review of the most recent developments in the treatment of skin findings.
