A case of granuloma pyogenicum presenting as an intravascular mass: evaluation by ultrasonography

Abstract

haematoxylin and eosin staining nor at immunohistochemical examination. All patients are still alive, except one patient who is dead of another cause, and free of local or distant recurrence after a mean follow-up of 4 years.SLNB is thus far a procedure which remains controversial in patients with melanomas of Breslow thickness less than or equal to 1 mm usually considered as 'good prognosis' lesions. 2,7 However literature reports a rate of positivity of SLN from 0% to 9.5% in melanomas of Breslow thickness less than or equal to 1 mm, with higher rate of positivity in regressive/ulcerative lesions. 3 In our study, we show the absence of microscopic lymph node involvement in regressive and/or ulcerated thin melanomas (Breslow thickness ≤ 1 mm, mean Breslow index = 0.59 mm). We conclude that SLNB was not useful in our series of thin melanomas, but further larger studies should be now focused on melanomas with Breslow index between 0.75 and 1 mm before concluding that SLNB procedure is not useful in thin regressive and/or ulcerated melanoma patients. 8 References1 Lens MB, Dawes M, Newton-Bishop JA, Goodacre T.

Intravenous lobular capillary haemangioma (pyogenic granuloma): A case report and a review of imaging findings as reported in the literature

“…The literature search identified 55 papers, which were all reviewed. Thirty‐eight of these were relevant . It has been generally accepted that the paper by Cooper et al ., describing a series of 18 cases, was the first description of the lesion, but review of the earlier case report by Meyers suggests that he was the first to identify the pathology.…”

“…Intravenous lobular capillary haemangioma (IVLCH), commonly known as intravenous pyogenic granuloma, is a rare benign lesion of veins, usually in the head and neck regions or upper limbs. Average age at presentation is 41 years with a reported age range of 12 to 79 years …”

Ultrasonographic features of an intravascular lobular capillary hemangioma originating in the basilic vein: Case report and literature review

“…We searched PubMed from January 1979 to August 2020 for "intravascular lobular capillary hemangioma" and "intravascular pyogenic granuloma," which yielded 44 papers, including nine reports on ultrasonography. [9][10][11][12][13][14][15][16][17] Grayscale ultrasonographic features of ILCH were almost uniformly described as a well-defined mass within the lumen of a vein, except for one case where ultrasound failed to identify the host blood vessel. 12 Although some lesions were reported as iso-echoic, most were mainly hypoechoic.…”
