COMMON SKIN LESIONS
HIDRADENITIS SUPPURATIVA
Skin fluid collection (*) in the groin region. Abbreviations: D, dermis; ST, subcutaneous tissue
PLANTAR WART
Fusiform hypoechoic lesion that corresponds to the wart (W). Abbreviations: E, epidermis; D, dermis; ST, subcutaneous tissue
BASAL CELL CARCINOMA
Hypoechoic solid lesion (*) that involves epidermis, dermis and the upper part of the subcutaneous tissue.
EPIDERMAL CYST
Anechoic cystic structure (*) that involves dermis and subcutaneous tissue. Abbreviations: D, dermis; ST, subcutaneous tissue
HEMANGIOMA
Solid heterogeneous lesion (*) that involves epidermis, dermis, and subcutaneous tissue. Abbreviations: D, dermis; ST, subcutaneous tissue
HEMANGIOMA COLOR DOPPLER
Increased blood flow within the lesion ( same case of figure 5)
PILOMATRIXOMA
Solid nodule (*) that involves dermis and subcutaneous tissue. The hyperechoic dots within the lesion corresponds to the calcium deposits. The nodule also presents an hypoechoic rim. Abbreviations: D, dermis; ST, subcutaneous tissue
NAIL PSORIASIS
Increased thickness of the nail bed and blurriness of the proximal part of the ventral plate. Abbreviations: NB, nail bed; DP, dorsal plate; VP, ventral plate; M, matrix; DPH, distal phalanx
GLOMUS TUMOR OF THE NAIL
Hypoechoic nodule (*, between markers) in the proximal nail bed that involves the matrix region . There is a deformation of the bony margin of the distal phalanx ( by extrinsic compression). Abbreviations : NB, nail bed; PL, plates, DPH, distal phalanx
GLOMUS TUMOR SIDE BY SIDE COMPARISON
Side by side comparison clearly shows the tumor on the left nail bed. Abbreviations as figure 9.
GLOMUS TUMOR SIDE BY SIDE IN TRANSVERSE VIEW
Side by side comparison in transverse axis shows the nodule (*) only present in the left nail bed
GLOMUS TUMOR BLOOD FLOW
Power angio in longitudinal view shows increased blood flow within the tumor ( in colors)
ARTERIAL VASCULAR MALFORMATION
US ( longitudinal view) shows tortuous vessels with turbulent flow ( arterial) in the subcutaneous tissue
VENOUS VASCULAR MALFORMATION
US (transverse view) shows multiple and tortuous vessels (*) in the subcutaneous tissue. All these vessels were easily compressed by the probe pressure. Abbreviations: D, dermis; ST, subcutaneous tissue
VENOUS VASCULAR MALFORMATION COLOR DOPPLER
Blood flow within the vessels ( in colors)
VENOUS VASCULAR MALFORMATION SPECTRAL CURVE ANALYSIS
Venous (monophasic) flow within the vessels
LYMPHATIC VASCULAR MALFORMATION
Anechoic pseudocysts (*) in the subcutaneous tissue. Abbreviations: D, dermis; ST, subcutaneous tissue
MIXED VASCULAR MALFORMATION ( CAPILLARY-LYMPHATIC)
Ill-defined structure in the subcutaneous tissue with anechoic lacunar pseudocysts (*, lymphatic component) and hyperechoic tisue ( capillary component) in-between. Abbreviations: D, dermis; ST, subcutaneous tissue
LIPOMA CLOSE TO THE BRACHIAL VESSELS
Hypoechoic mass (*) that corresponds to a lipoma in top of the brachial vessels. Abbreviations: BA, braquial artery; BV, brachial vein
TRICHILEMMAL CYST OF SCALP
Cyst (*) with echoes in the dermis and subcutaneous tissue of the scalp. Abbreviations: D, dermis; ST, subcutaneous tisue; EM, epicraneous muscle; BM, bony margin of the scalp
