Abstract Background Clear‐cell chondrosarcomas (CCCSs) constitute a very rare subtype of chondrosarcoma. CCCS may radiologically mimic chondroblastoma, and given the difference in surgical approach, it is important to distinguish these two entities preoperatively. Design Using the institutional digital records, we identified histologically verified CCCS between 1996 and 2013, where preoperative fine‐needle aspiration (FNA) cytology was available. Clinical characteristics were categorized...

Dwarf snakes of the genus Eirenis are derived from big, surface dwelling ancestors, considered to be similar to the genus Dolichophis. In Dolichophis–Eirenis dwarfing lineages, different structural implications of miniaturization on the feeding apparatus are observed, indicating that overcoming the challenge of miniaturization has achieved via different adaptations. Abstract As body size strongly determines the biology of an organism at all levels, it can be expected that miniaturization comes...

Among all extrinsic sources of cardiac innervation, the most abundant population of the nitrergic neurons resides in the rat nodose ganglia implying that NO is presumably involved in afferent innervation of the heart. Moreover, the sparse distribution of biphenotypic nitrergic/cholinergic neurons was identified within the motor vagal and sympathetic nuclei suggesting that NO may be involved in the transmission of preganglionic parasympathetic and sympathetic nerve impulses as well. Abstract...

The major finding of this study suggests that the abductor pollicis brevis consists of significantly greater type II muscle fibers when arranged contiguously with the palmaris longus tendon. This study supports evidence of the palmaris longus and abductor pollicis brevis acting as a functional digastric unit capable of enhancing thenar muscle actions. Abstract The palmaris longus (PL) tendon is used in surgical opponensplasty to restore functional hand movements in thenar paralysis. Although...

Although epaxial and hypaxial muscles in vertebrates are innervated by MMC and HMC neurons, respectively, some muscles have been found to receive dual innervation from both MMC and HMC. These muscles are situated between the epaxial and hypaxial muscles, and the term ‘midaxial muscles’ has been coined to refer to these transitional muscles. Abstract Trunk muscles in vertebrates are classified as either dorsal epaxial or ventral hypaxial muscles. Epaxial and hypaxial muscles are defined as...

The standard form of CD44 as a marker for invasion of encapsulated papillary carcinoma of the breast
Abstract Encapsulated papillary carcinoma (EPC), a rare variant of papillary carcinoma of the breast, is regarded as a transition form between carcinoma in situ and invasive carcinoma. Here, we tried to identify differences in immunohistochemical phenotype between 10 EPCs with invasive properties (EPC with invasion) and 17 non‐invasive EPCs (EPC). We immunohistochemically assessed the expression of hormone receptors, matrix metalloproteinase (MMP) 2 and MMP9, vascular endothelial growth factor (VEGF),...

Neoplastic PD‐L1 (nPD‐L1, clone SP142) expression remains unclear in cutaneous T‐cell lymphoma (CTCL), although it is well‐documented in classic Hodgkin lymphoma (CHL). Here, we report two cases of primary cutaneous large T‐cell lymphoma (PCLTCL) with CD30 expression that developed secondary nodal lesions morphologically mimicking CHL, and describe their PD‐L1 expression. Our two cases (52‐ and 60‐year‐old males) had long‐standing clinical courses of CTCL. Their PCLTCL with CD30 expression developed...
