A 4-year-old healthy boy presented with hypertrophy of the left thumb, which had disproportionately increased in size over the past 6 months. MRI revealed enlargement of the median nerve (Fig. 1, arrowheads) with a coaxial cable appearance with lipomatous components, diagnostic for lipofibromatous hamartoma [1]. Macrodystrophia lipomatosa was present, with subcutaneous fat hypertrophy of the thumb (Fig. 2, asterisk) and fat infiltration of muscles of the thenar eminence (Fig. 2, arrows).
