OBJECTIVES: Papular dermatoses commonly affecting the female vulva, such as molluscum contagiosum, syringoma, lymphangioma, folliculitis, verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis, often present with similar clinical appearances and are frequently misdiagnosed. This study aims to explore the clinical diagnostic value of reflectance confocal microscopy (RCM) in differentiating these conditions. METHODS: A retrospective analysis was conducted on RCM imaging and histopathological findings from lesion sites in 172 female patients with vulval papular dermatoses. RCM characteristics confirmed by biopsy were summarized and diagnostic clues were explored. RESULTS: RCM diagnosis was consistent with histopathological diagnosis in 147 out of 172 cases (85.47%). Molluscum contagiosum, syringoma, lymphangioma, and folliculitis all exhibited cystic-like structures under RCM, differing in the location of the structures, wall characteristics, internal contents, and reflectivity. Verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis lacked such structures. Verruca vulgaris showed distinctive low-refractive vacuolated cells in the spinous layer; bowenoid papulosis exhibited mild cytologic atypia in the spinous layer; ectopic sebaceous glands were characterized by moderately to low-refractive, fish roe-like sebaceous lobules within the dermis. CONCLUSIONS RCM enables noninvasive, real-time, and dynamic visualization of key diagnostic and differential features of common vulvar papular dermatoses in women, offering high diagnostic value.

BACKGROUND

Molluscum contagiosum is a benign viral infection affecting children, sexually active adults, and immunocompromised individuals. Modified autoinoculation (MAI) is a procedure in which a solitary lesion of molluscum contagiosum lesion is inoculated in the affected skin to stimulate an immune response, thereby clearing the infection.

This study aimed to compare the efficacy and safety of modified autoinoculation versus curettage in the treatment of molluscum contagiosum infection.

This study was an assessor-blinded, randomized therapeutic trial performed at the Department of Dermatology of Jose R. Reyes Memorial Medical Center. 52 patients with newly diagnosed molluscum contagiosum that had not been previously treated were assigned randomly using computer-generated randomization to either curettage or MAI. 26 patients were allocated in each treatment group. Patients were followed-up every 2 weeks for 3 months and at 6 months to evaluate clearance and recurrence rates along with adverse events.

Curettage was significantly a more effective treatment than MAI in achieving higher clearance rates and reducing recurrences. Adverse events did not differ significantly.

While MAI was a less invasive alternative, curettage remains superior in terms of efficacy and recurrence prevention. However, MAI may still be considered for patients seeking a less painful procedure, especially in children and those with extensive lesions.

Wells' syndrome or eosinophilic cellulitis is usually observed in adults who present with pruritic, erythematous and edematous plaques associated with papules or vesicles. It is a rare inflammatory dermatosis of unknown etiology showing an eosinophil-mediated immune response. Classical histopathological features observed in patients are eosinophil-predominant inflammatory infiltration and marked dermal edema, along with ‘flame figures’. An 11-year-old boy presented with edematous plaques surmounted by vesicles on his abdomen and lower extremities. A month prior to presentation, these skin lesions occurred on other parts of his abdomen; however, they resolved spontaneously within a week. Skin biopsies from the recurrent lesions showed features consistent with Wells' syndrome and a few molluscum bodies in the epidermis. Laboratory tests showed peripheral eosinophilia. We concluded that Wells' syndrome in this young patient was caused by preceding molluscum contagiosum infection.
