“…The differentiation between diffuse and nodular hyperplasia alone as mentioned by the authors and earlier by others [8][9][10] seems insufficient [6]. As indicated before [17], it is important to differentiate within diffuse enlarged glands on the basis of their fat content [7]. Welsh et al [18] used the gland with the lowest density in the "density test."…”

“…Tissue selection prior to immediate autotransplantation in all patients with renal hyperparathyroidism is importan t to prevent graft-dependent hyperparathyroidism [ 16]. Rothmund and Wagner [17], Akerstr6m et al [14], and Tominaga et al [10] recommended the smallest gland for autotransplantation. We do not agree entirely becaus e the smallest gland is often (but not always) morphologically and functionally the "optimal" one [2].…”

Invited commentary

“…The best way to avoid the complications of permanent hypocalcemia is immediate (prophylactic) autotransplantation of normal parathyroid tissue during thyroid surgery or extended surgery for advanced neck tumors [1,2]. After total parathyroidectomy for primary and secondary parathyroid hyperplasia, immediate autotransplantation of fresh parathyroid hyperplastic fragments is the treatment of choice after special tissue selection [2,5,6].…”
