Neurogenic tumor is the name given to any tumor that arises from the nerve tissue or its coverings. Neurogenic tumors of Sino-nasal cavity are a very rare entity. The most common types are Schwannomas and Neurofibromas and the plexiform subtype is one form of these neuroendocrine tumors. We report the case series of two such cases of a plexiform neurofibroma of the nasal tip, which were excised via an open rhinoplasty approach.

Amyloidosis is a benign, indolent condition which presents with an abnormal deposition of extracellular protein in various organs of the body. It usually presents with hoarseness of voice to an otolaryngologist. A sits clinical appearance mimics an early laryngeal cancer. It remains a diagnostic challenge to the clinician. It is essential to differentiate a primary laryngeal amyloidosis from malignancy to have a holistic approach towards the management of the disease. Here in this article, a case is reported in order to have a better outlook about this rare condition and to differentiate it from laryngeal malignancy for an effective management and cure.

Augmentation of nasal tip and/or dorsum forms the keystone of any Septorhinoplasty surgery. The grafts available for augmentation are numerous and varied. Choice of the graft depends upon the type of augmentation required, patient characteristics and, most importantly, the surgeon. In this article, we would like to present our experience with various augmentation grafts. In our experience, autografts are best grafts for augmentation. But in cases of revision surgeries or deficiency of autografts, allografts can be used. Our choice of allograft is Poly Diaxone Sheath or PDS.

Thornwaldt cyst is benign, mucosal congenital cyst which is located in upper nasopharynx. It developed in nasopharyngeal bursa if opening of bursa is occluded due to infection or inflammation. It is rare congenital cyst present in nasopharyngeal bursa. Its incidence is 3% in adults [1]. The usual age of presentation is 2nd and 3rd decade [1]. It is usually asymptomatic and incidental finding on MRI but it can present as nasal obstruction, post nasal drip, halitosis, occipital headache, foreign body sensation in throat [1] [2]. Here we are presenting a case report of 23 years old male presented with foreign body sensation in throat since 5 months. On oral and nasal endoscopic examination cystic mass in nasopharynx seen, bulging in oropharynx. MRI shows cystic mass arising from left side of nasopharynx popping up in oropharynx. Cyst then excised with diode laser with both endonasal and transoral approach with zero degree rigid endoscope. Histopathology confirmed the cyst as thornwaldt cyst.

Cardiac papillary fibroelastomas(CPFs) are the second most common primary cardiac tumors and the most common cardiac valvular tumors. Although they are histologically benign and usually asymptomatic, CPFs can lead to serious and life-threatening complications like myocardial infarction, stroke, pulmonary embolus, cardiac arrest etc. CPFs represent a rare entity in clinical medicine and literature regarding their management is limited. We report two cases which illustrate such complications arising from undiagnosed CPFs on the aortic valve. We further stress on the importance of identifying CPFs early so that they can be managed appropriately based on recommendations from the available literature.

Random amplified polymorphic DNA (RAPD) markers were used to study the DNA polymorphism in Indian mungbean cultivars. A total of 60 random primers were used in the study and 33 of them generated reproducible RAPD patterns. Amplification of genomic DNA of most popular 24 Indian mungbean cultivars with these RAPD primers yielded 249 fragments that could be scored, of which 224 were polymorphic, with an average of 7.0 polymorphic fragments per primer. Number of amplified fragments with random primers ranged from 2 (OPI 9) to 17 (OPD 7). Percentage polymorphism ranged from 33% (OPX 5) to a maximum of 100% (OPX 4, OPX 6, OPX 13, OPX 15, OPX 19, OPD 5, OPD 7, OPD 20, OPI 4, OPI 6, OPI 13, OPI 14, OPI 18 and OPF 1), with an average of 90%. The Jaccard’s similarity indices based on RAPD profiles were subjected to UPGMA cluster analysis. And genotypes grouped in two major groups. Sixteen out of 24 released cultivars grouped to cluster I. This indicated the narrow genetic base in the Indian mungbean cultivars used in the study. The details of diversity analysis and possible reasons for narrow genetic base in mungbean cultivars are discussed in the present study.
