Description of two new species of Myctolaimus Cobb, 1920 (Nematoda: Cylindrocorporidae) from Northern India

This paper deals with description of two new species of Myctolaimus Cobb, 1920 obtained from ditch samples from Kishtwar, Jammu and Kashmir, India. M. neolongistoma sp, n. is characterized by its medium-sized body (L= 0:60-0.67; a= 217-26.1;b- 4.8-5.1;c= 4.8-5.3, c'= 6.9-7.0; V= 48.2-51.3) with fine longitudinal striations, petalloid cheiforhabdions, isthmus equal or slightly smaller than basal bulb, and males with 20-24 µm long spicules and ten pairs of genital papillae. The other species, M. kishtwarensis sp. n., is characterized by its large body (L= 0.86-1.14; a= 25.1-30.9; b= 5.5-6.8; c= 4.4-5.9; d = 7.2-10.2; V= 43.1-47.8), six radiating cheilorhabdial arms, isthmus larger than basal bulb and males with 24-28 µm long spicules, and nine pairs of genital papillae

The new species is characterised by its medium-sized body; stoma armed anteriorly with a large daw-shaped dorsal tooth and two smaller conical, sub-ventral teeth; pharynx with pyriform valvate basal bulb; a pair of pseudocoelomocytes posterior lo cardia; didelphic genital system with reflexed ovaries; vagina with round sclerotised thickenings; rectum with thick sclerotised posterior lining; and tail with a long and cylindroid terminal spinneret

Four new species of Leptonchoidea (Nematoda: Dorylaimida)

Basirotyleptus upicus n.sp. is described from soil around the roots of grasses from Uttar Pradesh, India. It is close to B. basiri and B. penetrans but is distinguished by having a longer and narrower body and a longer oesophagus and tail. B. soueastus n.sp. (male unknown) is described from soil around the roots of durin [? Durio zibethinns] trees from Penang, Malaysia. It differs from B. caudatus and B. lieberi, to which it is close, in size of body, odontostyle, odontophore, tail and in the mono-opisthodelphic gonad. Dorylaimoides micoletzkyi is recorded from India for the first time. D. ilyasi n.sp. is described from soil around the roots of Artocarpus heterophyllus from Penang, Malaysia. It is close to D. constrictus and D. brevidens but is characterized by body, oesophagus, spicule, tail and amphidal aperture size and by the position of the vulva. Tylencholaimus innebus n.sp. (male unknown) is described from soil around the roots of mosses and ferns from the Jhoolaghat hills, Uttar Pradesh, India. It is distinguished from T. teres and T. crassus, to which it is close, by body and oesophagus size, vulva position, the smaller odontostyle and the long filiform tail

Adnexal Tumors of Skin: An Experience at a Tertiary Care Center at Delhi

Background: Adnexal skin tumors are a heterogeneous group of uncommon tumors usually misdiagnosed clinically due to a huge variety of types and their variants. Histopathology usually helps in establishing the diagnosis. Aims: The study was undertaken to analyze the morphological, clinical, and histological features of adnexal tumors (ATs) of the skin at our center over a period of 4 years.Subjects and Methods: retrospective study was conducted over a period of 4 years (April 2010–March 2014), comprising 25 ATs of skin diagnosed in the Department of Pathology, Hamdard Institute of Medical Sciences and Research, Jamia Hamdard, New Delhi. All the consecutively reported AT cases were reviewed and reclassified as AT arising from sebaceous glands, hair follicles, or sweat glands. The concordance of clinical and histopathological diagnosis was also assessed.Results: Most of the ATs were benign (24/25) with head and neck being the most common location (72%). Nearly 56% of the tumors exhibited sweat gland differentiation,  28% hair follicle differentiation, and sebaceous gland tumors accounted for 16%. The most common varieties of tumors encountered in the present study included hidradenoma papilliferum and pilomatricoma. The concordance between clinical and histopathological diagnosis was found to be 50% approximately.Conclusions: ATs of the skin are rare neoplasms with benign tumors being far more common. They are often misdiagnosed clinically, so histopathology remains the gold standard for establishing an accurate diagnosis of skin ATs.Keywords: Adnexal tumors, hair follicle differentiation, sebaceous, sweat glan
