Chondroid Syringoma

Chondroid syringoma is a benign mixed tumour arising from the sweat glands which can be apocrine (found throughout the surface of the eyelid) or eccrine with a mean age of presentation being 50 years. Here we report two cases of chondroid syringoma of the upper eyelid, one in a young male patient and the other in an elderly woman. Both cases had well-defined lesions involving upper eyelid in the sub-brow region, underwent excisional biopsy, and histopathological findings were consistent with an apocrine type of chondroid syringoma in one case and eccrine type of chondroid syringoma in the second case. It is important to be aware of this entity as a rare cause of eyelid lesion due to the fact that although it is a benign neoplasm, incomplete excision may be associated with recurrence or malignant transformation.

Immunohistochemical Studies

Background: The benign fibrous histiocytoma (BFH) is a mainly dermal neoplasm composed of a mixture of fibroblastic and histiocytic cells. It is usually reported as occurring on the extremity, retroperitoneum or orbit but not commonly in the other head and neck regions.Methods: A ten-year old girl presented with a right external auditory meatal mass for 6 months. Clinical examination showed a small, firm non-tender swelling on the antero-inferior part of the cartilagenous external auditory canal. An excisional biopsy was performed without complication.Results: Clinical and histopathological examinations with immunohistochemical studies were consistent with the diagnosis of BFH of the external auditory canal. There was no local recurrence to date.Conclusions: BFH is an uncommon benign neoplasm of the head and neck and none has been previously described occurring in the external auditory canal. Complete local excision is the mainstay of treatment with excellent prognosis.  DOI: http://dx.doi.org/10.3329/bjo.v18i1.10424  Bangladesh J Otorhinolaryngol 2012; 18(1): 77-80

<p class="abstract"><span lang="EN-IN">Chondroid syringoma, is a benign neoplasm of sweat gland origin with an overall reported incidence of 0.01-0.098 percent. These tumours being rare can easily be misdiagnosed and should be included in the differential diagnosis of any slowly growing nodule in the skin of the face. The diagnosis is confirmed after histopathologic examination of tissue obtained by excisional biopsy. Treatment of choice is local surgical excision with a cuff of normal tissue, in order to prevent recurrence. We present a case of chondroid syringoma of the face (nasomaxillary groove), highlighting the rarity of the tumour and the surgical incision resulting in excellent cosmetic result.</span></p>

Benign Course

Pancreatic cysts are more common than before, largely because of widespread abdominal imaging. Pancreatic cystic neoplasms (PCN) are relevant to risk selection on 2 counts: they constitute more than 50% of all pancreatic cysts and, in contrast to the other 2 cyst types, are capable of malignant transformation. The majority of PCNs are benign at time of diagnosis and will follow a benign course. The challenge is to identify those PCNs that are malignant or will undergo malignant transformation with time. The purpose of this article is to provide pointers that can help meet this challenge while also summarizing the ongoing debate about their optimal management.

Radical Interaction

The theory of the body I want to explore here, assumes that researcher and researched are part of the same flesh of the world and can be understood in radical conjunction and not in duality. An interview is examined, first from the lifeworld (nursing) research paradigm and thereafter on the hand of Merleau-Ponty's concept of the reversibility of touching and being touched, wherein ‘subject’ (who touches) and ‘object’ (who is touched) are radically interrelated and coconstituted. Merleau-Ponty develops his reflections on this radical interaction as the ‘chiasm’. Although investigating the ‘chiasm’ can be seen as lifeworld research, the more common lifeworld approach only leads to rich description, which lacks the radical relational understanding of Merleau-Ponty's insights. I believe that acknowledgement of the chiasms of interrelationship reveals complex processes of enfoldment taking place between researcher and researched, writer and reader. All of them are enclosed in what Merleau-Ponty called the enfoldments or flesh of the world; which makes it very difficult to determine who touches whom and who is touched by whom. Research, when it tries to see, interpret and study the other, focuses on the visible of touching and being touched; but these inherently carry with them the invisible of the same actions. The consequences of these relationships for my study of a specific elderly woman are explored here.

A 7-year-old female presented with left upper eyelid swelling following pars plana deep vitrectomy and silicone oil injection 1 year before admission. The left upper eyelid had mechanical ptosis and on palpation there was a lobulated mobile mass in the lateral portion of eyelid. Computed topography scan showed multiple isodense masses with silicone oil in vitreous in the eyelid and orbit; histopathology after excisional biopsy proved the silicone oil migration. Silicone oil migration followed by vitrectomy may be due to leakage from the site of initial wounds or vitrectomy ports. It is important to suspect extraocular silicone oil migration in patients who presented with eyelid mass-like lesions with a history of silicone oil injection following pars plana deep vitrectomy.

Four characteristics, namely, skin thickness, the number of sweat glands per square centimeter of skin, the volume of sweat glands and the depth at which these sweat glands were located were investigated in the three genotypes of Hereford cattle.Of the four characteristics studied, only skin thickness differed significantly among the three genotypes. The dwarfs had the thinnest skin and the normal animals had the thickest skin. The heterozygotes showed intermediate values. No significant differences were revealed among the three genotypes for the other three characteristics.

AbstractWinter growth of young male red deer can be increased by exposure to 16 h of light (L) and 8 h of dark (D) per day (16L: 8D). This study tested the duration of photoperiod required for this growth response, determined if the time to reach slaughter weight can be reduced and monitored plasma IGF-1, prolactin and reproductive development. Fifty male calves were allocated to five equal groups. Four groups were housed indoors and for 33 weeks from the winter solstice (22 June, southern hemisphere) until 11 February were placed under either 16L: 8D (16L), 13·25L: 10·75D (13L), 10·751:13·25D (111) or 8L: 16D (8L) photoperiods. The fifth group of deer (OC) remained outside in a gravelled enclosure. All groups were given a pelleted diet ad libitum. Group food intake was recorded daily, individual live weight was measured weekly and testes diameter and blood samples taken at weekly or 2-week intervals.Plasma prolactin concentrations in 16L increased within 4 weeks of treatment and were different (P < 0·001) between groups from 14 August to 4 September. IGF-1 increased in both 16L and 13L 4 weeks after treatments and then increased further in 16L above that of 13L (P < 0·01). All groups grew at the same rate for the first 7 weeks. 16L then gained more weight (P < 0·001) than the other groups over the next 19 weeks (50·7 kg v. 38·5 for 13L, 35·7 for 11L, 37·0 for 8L and 37·4 for OC; s.e.d. 3·76). Food intake was positively related to growth rate in a similar way among the inside groups (P < 0·001), however there was a higher energy requirement outdoors (P < 0·05). A target live weight for slaughter of 95 kg was reached 7 weeks earlier for 16L than the other groups (P < 0·01). Testes diameter of 16L was larger than in the other groups from 13 November until 24 December (P < 0·001). The growth oflSL slowed from 1 January while that of OC increased and the live weight ofOC was equal to 16L by the end of the experiment. OC also had the largest testes diameter from 5 February onwards (P < 0·01). The live-weight increase in OC was associated with increases in both prolactin and IGF-1 levels.This study confirmed that 16L: 8D stimulates rapid growth of young male red deer during winter for sufficient time to achieve an earlier slaughter date. The live-weight advantage was lost by late summer however. The increased growth rate was mediated by food intake and associated with increases in IGF-1 and prolactin and earlier reproductive development. Photoperiods of 13 h of light per day or less did not stimulate growth and increases in IGF-1 and prolactin were of a lower amplitude than under 16L: 8D.

ObjectivesMalignant transformation of mature cystic teratoma (MCT) is rare. Unlike squamous cell carcinoma (SCC) in MCT, the other types of neoplasm in MCT have not been discussed in publications. We analyzed the clinical characteristics and prognosis of the other types of neoplasm (non-SCC) compared with those of SCC.MethodsA systematic literature search of literature published from 2000 to 2017 was conducted in PubMed, Web of Science, and Scopus. We reviewed case series that included all pathological types of malignant transformation.ResultsA total of 155 cases from 15 case series, including our cases, were included. Of the cases, 90 (58%) were SCC and 65 (42%) were non-SCC, including adenocarcinoma, carcinoid tumor, thyroid carcinoma, sarcoma, adenosquamous carcinoma, melanoma, sebaceous carcinoma, oligodendroglioma, signet ring cell carcinoma, and transitional cell carcinoma, in descending order of frequency. The mean ages of patients with SCC and non-SCC were 50.5 and 48.9 years, respectively. The mean tumor sizes were 14.7 cm in SCC and 13.9 cm in non-SCC. Surgical approaches were similar. First-line chemotherapy for epithelial ovarian cancers was the most commonly used regimen in SCC and non-SCC. Overall survival did not differ significantly, showing better prognosis in stage I and poor prognosis in stages II, III, and IV. A difference in overall survival was observed among pathological types of non-SCC.ConclusionsClinical characteristics and outcomes did not differ significantly between SCC and non-SCC. However, chemotherapy regimens differed to some extent, and the possibility of difference in overall survival among pathological types of non-SCC was suggested.

The sweat glands are important in thermoregulation of cattle in a warm environment as they help dissipate heat through evaporation. Studies on gland histology are important to define its secretion potential and the capacity of perspiration and heat removal. The objective of this study was to determine, by histomorphometry, glandular epithelium height, the depth of the gland, length of the glandular portion and number of glands per cm2 of the sweat glands of the three age groups of Nellore cattle. Thirty females were used in this study. They were equally divided into calves, heifers and cows. Histological sections were obtained and analyzed by digital images in Trinocular BX40 Olympus microscope coupled to an Oly - 200 camera, connected to a computer. The images were obtained with microscope with 2x, 4x, 10x and 40x magnification objectives. The measurements were performed using HL Image 97 program. The height of glandular epithelium, depth of the glands, length and density of the glandular portion per cm2 , were all analyzed. The calves showed greater height of the glandular epithelium than heifers (P = 0.0024), and cows (P = 0.0191). The depth of the gland was not influenced by age. Cows had higher length of secretory portion than heifers (P = 0.0379) and calves (P = 0.0077). Heifers had a greater number of sweat glands per cm2 of skin than cows (P = 0.023). In cattle, the height of glandular epithelium and the density decreases as animals get older. On the other hand, the length of the secretor portion increases but with no changes in the depth of the sweat glands
