BACKGROUND: Positron emission tomography (PET) is an examination based upon the uptake of a radioactive tracer by hypermetabolic cells. It is primarily used in tandem with tomodensitometry (PET-TDM) for @entity5 staging because of its high sensitivity and specificity for the detection of metastases. However, unusually high uptake may occur with @entity5 , including @entity1489 . Herein, we report an extremely rare case of pathological uptake levels resulting from @entity9284 . @entity1 AND METHODS: A 55-year-old male @entity1 with @entity957 was referred to us following the discovery of an area of high marker uptake following PET-TDM and corresponding to a @entity272 . No other areas of suspect high uptake were seen. The lesion was surgically excised and histological examination indicated @entity9284 . The histological appearance was that of standard @entity9284 without any notable mitotic activity. DISCUSSION: PET-TDM is an examination that enables diagnosis of @entity5 . However, rare cases have been described of increased marker uptake by benign cutaneous @entity5 such as histiocytofibroma, @entity17390 and @entity6205 . To date, there have only been only very few cases of increased uptake due to @entity9284 . CONCLUSION: This extremely unusual case of increased @entity413 uptake in PET-TDM due to @entity9284 that the hypermetabolic activity detected by this examination is not necessarily synonymous with @entity5 and that confirmation by clinical and histological findings is essential. The reasons for increased metabolic activity within such @entity5 are not known.
