Great Cases From My Files

Description

In this presentation, the speaker shares a series of clinical cases, primarily focusing on various dermatological conditions and their associated syndromes. The first case discusses a woman with facial white lesions diagnosed as fibrofolliculomas, indicative of Birt-Hogg-Dubé syndrome, which has both skin and internal manifestations including pulmonary cysts and renal cancer. Following this, the presentation covers hand, foot, and mouth disease in adults due to Coxsackievirus A6, characterized by severe lesions and systemic symptoms. Subsequent cases include painful lesions in a patient with incontinence of pigment, leading to keratoacanthomas, and a young man with idiopathic thrombocytopenic purpura manifesting as black oral lesions. The discussion touches upon unique presentations like recurrent follicular pustules linked to viral infections and actinic folliculitis, with insights into recent studies revealing new patterns and conditions related to dermatology. Throughout, the speaker emphasizes clinical recognition, effective diagnosis, and patient management, encouraging participation and discussion from the audience regarding these conditions.

Conclusions

  • Birt-Hogg-Dube Syndrome is characterized by a triad of skin findings, including fibrofolliculomas, trichodiscomas, and acrochordons, with autosomal dominant inheritance.
  • The understanding of internal manifestations associated with Birt-Hogg-Dube Syndrome was realized only decades after the syndrome's initial description.
  • Patients with Birt-Hogg-Dube Syndrome present with skin papules in their 20s and 30s, with serious internal complications like pulmonary cysts and pneumothorax starting in late adolescence or early adulthood.
  • Renal cancers associated with Birt-Hogg-Dube Syndrome typically manifest in the 50s and have a lower aggressiveness compared to other hereditary renal cancers, suggesting a careful monitoring approach rather than aggressive initial surgical interventions.
  • Routine annual scans for kidney and lung complications are recommended for individuals with Birt-Hogg-Dube Syndrome due to their significantly increased lifetime risks.
  • There is a notable mutation in the folliculin gene associated with Birt-Hogg-Dube, which serves as a tumor suppressor, emphasizing genetic testing for family patterning in symptomatic individuals.
  • Recent findings indicate the existence of a PRDM10 mutation syndrome that overlaps with Birt-Hogg-Dube, characterized by different tumor presentation and behavioral patterns of associated cancers, necessitating further research and potential shifts in patient management protocols.
