Congenital granular cell epulis of newborn: importance of prenatal diagnosis

Congenital granular cell epulis is a rare benign lesion usually arising as single mass from the alveolar ridge of maxillary bone of female newborns, composed of polygonal granular cells that typically stain negative for S-100, in contrast to the adult counterpart. Larger lesions can disturb breathing and breast-feeding, requiring surgery. Prenatal diagnosis is achieved in few cases, even if this would be important for best management of delivery and therapy. Here we present a case of multiple CGCE in a female newborn discovered at birth, together with a brief review of pathogenesis, differential diagnoses and treatment implications of early diagnosis.

Congenital cutaneous non-neural granular cell tumor mimicking herpetic infection: Case report and review of the literature

We present a case of a female neonate with a cluster of six skin colored to yellowish pseudovesicular papules on her right forearm present since birth, initially thought to be a herpes simplex virus infection. Punch biopsy with immunostaining revealed a diagnosis of S100-negative, CD163-positive congenital cutaneous non-neural granular cell tumor. Only four other reports are presented in the literature of this entity, three of which also presented on the arm with somewhat similar clinical findings. We briefly reviewed the subtypes of classic and S100-negative non-neural granular cell tumors.

Nonepithelial Tumors and Tumor-like Lesions of the Skin and Subcutis in Children

This overview of mesenchymal tumors presenting in the skin and/or subcutis in children brings together the range of neoplasms and hamartomas which are seen in this age-group. It is not surprising from the perspective of the pediatric or general surgical pathologist that vascular anomalies, including true neoplasms and vascular malformations, are the common phenotypic category. Since there is considerable morphologic overlap among these lesions, clinicopathologic correlation may be more important than for many of the other mesenchymal tumors. The skin and subcutis are the most common sites of clinical presentation for the infantile myofibroma which is the most common of fibrous mesenchymal tumors in children. Several of the other mesenchymal tumors are more common adults-like dermatofibrosarcoma protuberans, but nonetheless have an important presence in children, even as a congenital neoplasm. A lipomatous tumor in a young child should be considered as a possible manifestation of an overgrowth syndrome.

A thoracic parasternal granular cell tumor in a child: About one case and review of the literature, discussion about treatment guidelines, is complete resection compulsory?

Granular cell tumor is a well known soft tissue tumor, very rare in children; we describe here the first case of GCT in this particular location in a child. The diagnostic is easily done with histopathology. The treatment is based on the complete resection, no other validated treatment exists. We reviewed the literature to find out if it would be safe to consider a simple follow-up after partial resection of the tumor.
