Childhood Asymmetry Labium Majus Enlargement (CALME): Description of Two Cases.

Abstract：

:Background: Childhood asymmetry labium majus enlargement (CALME) is an uncommon, benign condition that occurs in pre- and early pubertal girls and is characterized by a painless, fluctuating, non-tender labial swelling with normal overlying skin. Recognition of this benign condition is essential. Differentiation with several other diseases that mimic CALME and require different diagnostic and therapeutic approaches is mandatory. Two cases of CALME are described in this report. Differential diagnoses and therapeutic approaches are highlighted. Case presentation: The first case was an 11-year-old Caucasian girl referred to our hospital for the evaluation of right labium majus, which showed a palpable, painless, soft, non-tender, non-erythematous enlargement measuring approximately 2 cm with indistinct borders. Ultrasound showed a mass 23 × 18 × 12 mm in diameter. Surgical excision of the mass was performed and in the histopathological evaluation, the tissue specimens were composed of haphazardly arranged vascular channels, adipose tissue and nervous elements that were components of the vulvar soft tissue and were compatible with the diagnosis of CALME. Case 2 was a 6-year-old Caucasian girl who presented a post-traumatic painless mass of left labium majus swelling that progressively increased in volume. Ultrasound study evidenced an ill-defined heterogeneous echotexture mass 26 × 15 × 10 mm in diameter and magnetic resonance imaging confirmed these findings. Histopathological examination was performed after bioptic sampling evidencing normal constituents of vulvar soft tissue, including fibroblast, collagen, adipose tissue, blood vessels and nerves compatible with CALME. Conclusions: CALME is a particular clinical condition that occurs mainly in pre-pubertal girls and has a benign course but poses numerous problems in differential diagnosis that can be solved only with careful clinical observation and with a careful use of radiological imaging techniques. Our cases, in agreement with recent literature, suggest that radical excision is not recommended and that surgical biopsy should be taken into consideration only in cases of doubt.
