1/12. Blue rubber bleb naevus: case report and literature review.Blue rubber bleb naevus syndrome is a rare cutaneous-digestive angiomatosis, described first by William Bean in 1958. Today, there are more than 200 cases published. The dangers of this syndrome include angiomata in the brain, kidneys or lungs (due to vasculature obliteration by in situ thrombosis). patients are scanned with technetium-labelled red blood cells in order to identify the affected organs. Multiple techniques are used to treat the lesions by gastrointestinal endoscopy.- - - - - - - - - - ranking = 1keywords = naevus syndrome, naevus (Clic here for more details about this article) |

3/12. Common blue naevus with satellite lesions: possible perivascular dissemination resulting in a clinical resemblance to malignant melanoma.We report a case of common blue naevus with polymorphous guttate and linear satellite lesions, thereby mimicking peripherally spreading malignant melanoma. Histopathologic examination showed that the naevus cells are clustered around blood vessels in the primary as well as satellite lesions, suggestive of spreading of the naevus cells along the perivascular space. Such biological behaviour resulting in a clinical manifestation of a malignant melanoma-like lesion is a rarity in common blue naevus, a benign cutaneous disorder that is devoid of a malignant potential, and has not been described before.- - - - - - - - - - ranking = 1.258459703845keywords = naevus (Clic here for more details about this article) |
4/12. Cellular blue naevus of the scalp with brain invasion.A case of a 28 year old woman with an intracranial cellular blue naevus (CBN) which was believed to be the extension from a pigmented skin/scalp lesion is reported. There was no similar pigmented skin lesion noted on other parts of her body. Radical intervention, including wide excision of the affected skin of the scalp, removal of the underlying pigmented skull bone and wide excision of the pigmented dura, together with wide excision of the intracranial mass, were performed. The skin defect was covered by rotation flap and free skin graft. The dura was closed by grafting with fascia lata. The skull defect was left open and would be repaired later at a second planned surgery.- - - - - - - - - - ranking = 0.7865373149031keywords = naevus (Clic here for more details about this article) |
5/12. Epithelioid blue naevus of the genital mucosa: report of four cases.Epithelioid blue naevi are an unusual cytological variant of blue naevus that have been recently described mostly in patients with the carney complex, although they may also occur in isolation. This variant of blue naevus is composed of melanin-laden polygonal epithelioid melanocytes situated within the dermis. The neoplastic cells show no maturation with progressive depth of dermal infiltration and, in contrast with the usual stromal changes in blue naevi, epithelioid blue naevi exhibit no dermal fibrosis. We describe four cases of epithelioid blue naevus located on the genital mucosa in four patients with no evidence of the carney complex. Three male patients showed an epithelioid blue naevus on the mucosa of the glans penis and a female patient had a lesion of the right labium minoris. Histopathologically, the lesions consisted of entirely intradermal melanocytic naevi composed mostly of heavily pigmented epithelioid melanocytes involving the dermis of the genital mucosa. Immunohistochemically, in all cases, epithelioid melanocytes expressed immunoreactivity for S-100 protein, HMB-45, Melan-A and MiTF antibodies.- - - - - - - - - - ranking = 1.258459703845keywords = naevus (Clic here for more details about this article) |
6/12. Blue naevus with satellitosis mimicking malignant melanoma.Blue naevus is an acquired benign melanocytic naevus. It is a firm, sharply defined dark blue to grey-black papule or nodule, which is likely to arise from the arrested dermal melanocytes in the dermis. In the last few years, blue naevus has attracted much attention due to the recognition of new entities and to its confusion with malignant melanoma. We report a 69-year-old man who developed a blue-black nodular lesion with satellitosis on his scalp. Although clinically it was thought to be a malignant melanoma, histopathological investigation and conservative methods such as dermatoscopy and power Doppler ultrasonography did not confirm this diagnosis. Histopathological examination excluded malignant melanoma, as there were no cellular atypia and mitotic activity in either the nodular lesion or the satellitosis. Doppler ultrasonography confirmed the benign nature of the lesion. Dermatoscopic examination showed homogeneous steel-blue pigmentation with individual blue globules, dots and some brown veils, and confirmed the histopathological diagnosis. To the best of our knowledge, our case is the third reported case of a blue naevus with satellitosis mimicking malignant melanoma.- - - - - - - - - - ranking = 1.258459703845keywords = naevus (Clic here for more details about this article) |
7/12. The use of selective lymphadenectomy in malignant blue naevus of the scalp.Malignant blue naevus (MBN) is a rare cutaneous tumour with a close biological resemblance to malignant melanoma. MBN spreads to regional lymph nodes, creating a dilemma in managing patients with clinically negative nodal basins. Sentinel lymph node (SLN) biopsy has evolved as a powerful staging tool by identifying occult metastatic nodal disease in patients with cutaneous malignancies. Here, we report a patient with MBN of the occipital scalp who underwent wide local excision together with preoperative lymphoscintigraphy and intraoperative radiolymphoscintigraphy and vital dye injection to identify all draining SLNs. No occult nodal disease was identified. This report adds to the growing body of literature supporting the role of SLN biopsy in staging individuals with cutaneous malignancies, including MBN.- - - - - - - - - - ranking = 0.7865373149031keywords = naevus (Clic here for more details about this article) |
8/12. Sclerosing 'mucinous' blue naevus.Abundant mucin deposition is an unusual finding in melanocytic naevi. We describe the first example, to our knowledge, of a sclerosing blue naevus with an abundant mucinous stroma in two unrelated patients. This uncommon variant of blue naevus should be differentiated from desmoplastic-neurotropic melanoma, in which the presence of mucin stromal deposition is a more typical finding.- - - - - - - - - - ranking = 0.94384477788372keywords = naevus (Clic here for more details about this article) |
9/12. Blue rubber bleb naevus syndrome associated with cortical blindness.An 83-year-old woman was admitted for investigation of sudden loss of vision. Extensive plum-purple papules and nodules involved her skin and lips but not mucosae. A cutaneous biopsy demonstrated irregular vascular cavernous channels in the dermis and subcutis; deeper vessels displayed smooth muscle. Blue rubber bleb naevus syndrome was diagnosed. This patient had no gastrointestinal symptoms, no family history of blue rubber bleb naevus syndrome, and only developed cutaneous signs after 60 years of age. magnetic resonance imaging of the brain found multiple cerebral and cerebellar cavernomas with two larger foci of haemorrhage in both occipital lobes, with the largest in the right occipital lobe being associated with calcification. These most likely represent bleeding in relation to cavernomas believed to be the cause of decreased vision, predominantly in the left eye.- - - - - - - - - - ranking = 2.2246208884651keywords = naevus syndrome, naevus (Clic here for more details about this article) |
10/12. Homogeneous blue pigmentation in dermatofibroma simulating a blue naevus.A case with a pigmented skin lesion that was diagnosed as a blue naevus on clinical and dermoscopic grounds and histopathologically confirmed as a dermatofibroma is presented. By means of this case, we define dermatofibroma as a new exception for 'homogeneous blue pigmentation' on dermoscopy.- - - - - - - - - - ranking = 0.7865373149031keywords = naevus (Clic here for more details about this article) |
