The core four - A panel of immunohistochemistry markers to diagnose and subtype testicular germ cell tumors.

Context: Immunohistochemistry (IHC) to differentiate germ cell tumors.

Aims: The aim of the study is to differentiate seminomatous and nonseminomatous germ cell tumors (GCTs) with morphological overlap using a minimal and affordable panel of IHC markers.

Settings And Design: This is a retrospective observational study.

Tracheal/Laryngeal Infiltration in Thyroid Cancer: a Single-Centre Experience.

Around 1/3 of patients of locally advanced carcinoma thyroid present with tracheal infiltration either alone or along with infiltration of other adjacent structures. Even though trachea is infiltrated, adequate resection is the main modality of treatment in these patients. We retrospectively analysed carcinoma thyroid patients who were operated at our institute, between January 2011 and December 2018, and underwent thyroidectomy with tracheal or laryngeal resection.

Primary Malignant Peripheral Nerve Sheath Tumor of the Trachea: a Case Report with Brief Review of Literature.

Malignant schwannoma, also called malignant peripheral nerve sheath tumor (MPNST), is a rare and aggressive tumor arising from the nerve sheath. We describe a rare case of endotracheal malignant peripheral nerve sheath tumor occurring in a middle-aged male who presented with asthma-like symptoms for 6 months with progressively increasing dyspnea. A computed tomogram (CT) scan of the thorax revealed near complete luminal obstruction of the trachea by a mass lesion at the level of the second and third tracheal rings.
