Malignant melanoma is a potentially lethal cutaneous malignancy. Melanoma in paediatrics is rare as compared to adult melanoma. The clinicopathological characteristics of paediatric melanoma are different from adult melanoma, and the presence of melanoma mimics which occurs frequently in children (Spitz naevi) resulted in diagnosis uncertainty.

Pyogenic granuloma (PG) is an acquired vascular lesion that affects the skin and mucosa. The term Lobular Capillary Hemangioma was subsequently adopted to more accurately reflect its biologic and histopathologic nature [1]. Clinically, PGs usually appear as single, small, red papules with a marked tendency for bleeding. Read More

Renal vascular lesions (RVL) are rare and their morphological spectrum remains largely unknown, particularly in children. In this study, we characterize the clinicopathological features of RVL in a cohort of twelve children. Seven lesions were classified as previously recognized entities: vascular malformations (four), papillary endothelial hyperplasia (two), and pyogenic granuloma (lobular capillary hemangioma) (one).

The paper presents an example of differential diagnostic studies for pyogenic granuloma and oral squamous cell carcinoma (SCC). In the described case immunohistochemistry with antibodies to Ki-67 and Gli1 was used as conventional histological procedure proved to be inconvenient for adequate diagnostics. The immunohistochemical study established increased proliferative activity of epithelial cells specific both pyogenic granuloma and oral SCC, but intensive Gli1 protein expression in membranes and cytoplasm of epithelial cells with malignant transformation allowed differentiation of these neoplasms.

Background: Pyogenic granulomas are benign, reactive, typically superficial vascular lesions that can be idiopathic or arise secondary to trauma, underlying vascular malformations, infections, physiologic or pathologic endocrine changes, and hormone therapy. Deep-seated/subcutaneous pyogenic granulomas (DSPG) are rarely seen in any age group. Pediatric DSPGs can be a clinical and pathologic challenge because these lesions mimic other vascular lesions, including kaposiform hemangioendothelioma, infantile hemangiomas and vascular malformations.
