Metastatic adamantinoma involving the spine is an extremely rare occurrence. In this case report, we present a patient with recurrent adamantinoma of the tibia which was found to have metastasized to the spine. The metastatic involvement was diagnosed pathologically, status post CT guided percutaneous core needle biopsy, performed after the patient returned with concerning symptoms and imaging findings suggestive of metastasis. The patient was ultimately treated surgically with vertebrectomy and reconstruction. A thoughtful review of this disease process is explored, emphasizing the pathology, imaging characteristics, and pertinent differential diagnostic considerations. While uncommon, knowledge of this rare disease process and its presentation can improve future patient diagnosis and outcomes.

“…There are sporadic case reports of adamantinoma of the rib, spine, calcaneum, metatarsal, and carpal bones [ 1 , 5 ]. To the best of our knowledge, there have been 14 case reports of adamantinomas arising in the femur [ 2 – 4 , 6 , 7 ].…”

Adamantinoma of the distal femur diagnosed 5 years after initial surgery: a case report

BackgroundAdamantinoma arising in the femur is extremely rare. We report a case of an adamantinoma occurring in the right medial femoral condyle that was diagnosed 5 years after the primary surgery.Case presentationA 74-year-old Asian woman first complained of right knee pain without any cause. Radiographs demonstrated a 4×4.5 cm osteolytic lesion in her medial femoral condyle. Magnetic resonance imaging revealed a lesion which showed low signal on both T1 and T2-weighted image, and enhanced signal with gadolinium contrast administration. She underwent a wide resection of the lesion and was reconstructed with a tumor endoprosthesis. On histological examination, the tumor showed clusters of spindle-shaped and squamoid epithelial cells among the fibrous stroma. Adamantinoma was considered, however, the diagnosis was inconclusive due to the unusual localization and her age. Moreover, it was difficult to exclude metastatic carcinoma. Five years later, she was diagnosed with an abnormal shadow occupying the upper lobe of her right lung in a routine physical examination. She subsequently underwent a resection of the lung mass which histologically showed proliferation of spindle-shaped and squamoid epithelial cells. The histological similarity of the lung tumor and the femoral tumor led to the diagnosis of adamantinoma arising in her right medial femoral condyle with metastasis to the upper lobe of her right lung.ConclusionIn this case report, we report the clinical, radiographic, and histological features of an adamantinoma arising in the distal femur with a review of the literature.

Первичные саркомы кости составляют менее 0,2% всех злокачественных опухолей человека [1,2]. Спектр нозологических форм костных процессов включает специ-фические злокачественные опухоли скелета, недиффе-ренцированные саркомы и мягкотканные саркомы -опухоли, гистогенетически типичные для мягких тканей. Специфические злокачественные опухоли объединяют остеосаркому, хондросаркому, саркому Юинга, адаман-тиному, хордому, злокачественную гигантоклеточную опухоль. Из них первые три опухоли в структуре заболева-емости костными саркомами составляют большинство -более 75% [1,2]. Частота встречаемости остеосаркомы, хондросаркомы и саркомы Юинга равна 35,1, 25,8 и 16% соответственно [1,2]. Мягкотканные саркомы чаще всего включают лейомиосаркому, ангиосаркому, синовиаль-ную саркому, липосаркому, злокачественную опухоль из оболочек периферических нервов [1, 2]. Метастазирова-ние костных сарком осуществляется преимущественно гематогенным путем -до 90% случаев [1]. Органом-ми-шенью для гематогенного метастаза являются, как прави-ло, легкие, реже -кости скелета, головной мозг [1][2][3]. Однако в малой части случаев метастазы поражают лим-фатические узлы. Метастазы в лимфатических узлах могут быть как солитарные, так и множественные [4,5]. Воз-можно метастатическое поражение не только «первого эшелона» лимфатической системы -регионарного аппа-рата, но и отдаленных групп лимфатических узлов, обна-руживаемых в средостении, забрюшинном пространстве, шее, парааортальной области [5][6][7]. Так, например, опи-саны метастазы остеосаркомы бедренной кости в лимфа-Васильев Николай
