Current concepts of ectopic nodal inclusions with special emphasis on nodal nevi

Anatomic Pathology / NODAL NEVI

Melanocytic nevi occurring in lymph nodes create diagnostic difficulty by mimicking metastases. Few studies describe nodal nevi in sentinel lymph nodes (SLNs) excised for melanoma. We evaluated 72 cases in which patients had undergone SLN biopsy for melanoma. Lymph nodes and cutaneous melanomas were evaluated according to a standard protocol. Nodal nevi were identified in 8 patients (11%). Of t...

Caudocranial conduction in the left auricle in nodal rhythm and in nodal ectopic beats.

As we described elsewhere (Wenger et al., 1950 and 1952) the pattern of aesophageal leads, as registered at various heights above the diaphragm, gives us the chance of drawing conclusions about the conduction in the left auricle. CEsophageal P waves at auricular levels contain well defined intrinsicoid deflections (Brown, 1936; Neuman, 1951; Schwartz, 1947; Wenger, 1947) and the time of their a...

Primary Stromal Sarcoma of Breast with Nodal Recurrence

  Although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. Sarcomas represent less than 1% of primary breast neoplasms. These tumors are at high risk of recurrence and are known to have poor prognosis. Surgical resection is the primary treatment for these lesions and axillary lymph node dissection is no...

On Nodal Sextic Fivefold

In this paper we prove the birational superrigidity and nonrationality of a hypersurface X ⊂ P of degree 6 such that the hypersurface X does not contain three-dimensional linear subspaces of P and the only singularities of X are isolated ordinary double points.
