Background: Squamous cell carcinoma (SCC) and adenocarcinoma are the most common esophageal cancers. Barrett’s esophagus is the change of esophageal stratified squamous epithelium to columnar cells which if remain undiagnosed follows the dysplasia – carcinoma sequence. The last two decades show a change in the histologic pattern of esophageal carcinoma. Adenocarcinoma is at majority rate than SCC in the West, however, in Asia, SCC is still the commonest cancer of esophagus. In this study, we aim to define a spectrum of premalignant and malignant neoplasms of esophagus in our region. Methods: This study was done at Dow Diagnostic Research and Reference Laboratory (DDRRL). All the cases of preneoplastic and neoplastic lesions of esophagus received during the period of 7 years (2009-2015) were reviewed. The data obtained were subjected to descriptive statistical analysis using SPSS version 21. Results: Out of 94 premalignant cases, 70 (74.5%) were diagnosed as Barrett’s esophagus, 23 (24.5%) as dysplasia and 1 (1.1%) as adenoma. From the total of 450 malignant cases, 395 (87.7%) were SCC, 54 (12%) were adenocarcinoma and a single case of leiomyoma was diagnosed. Grade II SCC was found to be most the common lesion. Conclusion: Barrett’s esophagus was more than dysplasia and showed male preponderance. SCC was the predominant esophageal cancer, which is similar to the other studies in our country. SCC was found more common in females than males and vice versa for adenocarcinoma. Majority of all the cases belonged to 41-60 years of age group.

Apocrine gland anal sac adenocarcinoma (AGASACA) is locally aggressive and highly metastatic to regional lymph nodes. The aim of this study was to evaluate the prognostic significance of Ki67 in surgically excised AGASACA. Prognostic impact of size, regional lymph nodes metastasis, hypercalcemia, histologic pattern, mitotic count, necrosis, inflammatory and lympho-vascular invasion, anisokaryosis and anisocytosis was also evaluated. Thirty-five dogs were included, twenty-four of which also had metastatic lymph nodes. When the entire population was evaluated, only metastatic disease spread to regional lymph nodes, and necrosis and inflammatory infiltration were correlated to prognosis. When only dogs with metastatic disease were evaluated, size, solid histologic pattern, presence of lymphatic and vascular invasion showed influence on prognosis. Ki67 index was not associated with survival time and disease free interval in any case. The results of this study showed that lymph nodes metastasis at diagnosis reduced disease free interval. Moreover, tumor size greater than 5.25 cm, presence of lymphatic and vascular invasion and a solid histologic pattern were associated with a shorter survival time in dogs with metastasis to regional lymph nodes. Ki67 expression was not significantly associated with prognosis, therefore it could not be considered as a prognostic factor in this tumor type, while the role of hypercalcemia remained unclear.

Abstract We report 2 cases of nonspecific postvaccinial dermatitis following smallpox vaccination. The patients presented with diffuse, pruritic, erythematous macules and papules 11 days (case 1) and 7 days (case 2) following routine smallpox vaccination. Biopsies of the lesions demonstrated spongiotic dermatitis without evidence of viral cytopathic changes. One case showed a pityriasis rosea–like histologic pattern. The exanthema resolved without sequelae with symptomatic treatment (case 1). Review of historical literature demonstrated the association of a variety of nonspecific cutaneous complications with vaccinia inoculation, including erythema multiforme, urticaria, and pityriasis rosea. The association of these various dermatitides with smallpox immunization is not well known and is likely underreported.

Abstract In this report, we document the histologic and clinical features of a previously undefined spindle cell variant of ameloblastoma that eventually behaved in a malignant fashion during a protracted course. The predominant histologic pattern was a well-differentiated, cellular, spindled epithelial proliferation arising in the maxilla of a 14-year-old African American girl. Over 19 years, the patient experienced numerous local recurrences, metastases to distant bones after 15 years, and finally bulky local recurrence with intracranial extension resulting in death. This ameloblastic malignancy histologically simulates a low-grade true sarcoma or an ameloblastic sarcoma, but differs in that the extensive spindle cell proliferation is epithelial, characterized by strong cytokeratin immunoreactivity and negative vimentin staining.

Abstract Context.—Gliosarcoma is a rare tumor of the central nervous system characterized by a biphasic histologic pattern, consisting of a gliomatous and a sarcomatous component, respectively. In most instances the sarcomatous component is represented by a fibrosarcoma, but other stromal malignancies have also been described. Osteosarcomatous differentiation in gliosarcoma has been rarely reported. Objective.—To review characteristic radiologic and histopathologic features of this rare neoplasm, to debate about possible differential diagnoses that should be taken into consideration, and to provide an overview of the potential histopathogenesis of gliosarcomas. Data Sources.—Relevant articles indexed in PubMed (National Library of Medicine) and reference medical texts. Conclusions.—Recent molecular studies suggest that sarcomatous and gliomatous components of gliosarcoma might be derived from a single precursor cell clone, progressing in 2 subclones with distinct morphologic features during tumor evolution. Nonetheless, events determining splitting of the original clone into 2 histologic populations remain to be investigated.

Introduction: Adenoid cystic carcinoma is a rare salivary gland malignancy that can occur in any part of the body, its clinicopathologic features are scarcely reported in locoregional literature. Therefore, in this study we aimed to evaluate the clinicopathologic features of adenoid cystic carcinoma in our population and to determine the association of age and site of its occurrence with histologic pattern and perineural invasion. Methods: We retrospectively analyzed 30 cases of adenoid cystic carcinoma that underwent surgical resections or biopsies from March 2009 to February 2020 at Liaquat National Hospital and Medical College, Karachi. Clinical and histopathological parameters including age, site, histological pattern and perineural invasion were determined and association between different parameters was analyzed. Results: Mean age of the patients was 30 + 16.1 years. Cribriform pattern was most common histologic pattern (63.3%) while head and neck region was the most common site of occurrence (83.3%). Perineural invasion which is one of the most important prognostic factors in adenoid cystic carcinoma was present in approximately half of the patients (46.7%). No significant association of age and site was found with histologic pattern and perineural invasion. Conclusion: Adenoid cystic carcinoma is a rare malignancy most commonly occurring in head and neck region with a high frequency of perineural invasion. No significant difference of histologic pattern and histologic prognostic parameter like perineural invasion was noted at different ages and different sites in our study.

ABSTRACT Aims To describe an unusual presentation of myxoid liposarcoma of oropharynx and a brief review of literature. Introduction Liposarcomas of head and neck are very rare. Its treatment and prognosis mainly depends on the site and the histologic pattern of the tumor. Case presentation The present case report describes a 65-year-old male with complaints of dysphagia, dyspnea, and a peculiar complaint of mass in the throat which turned out to be a low-grade myxoid liposarcoma arising from right lateral wall of oropharynx extending intraluminal in the esophagus, compressing posterior wall of trachea. The mass was successfully excised surgically and postoperative period was uneventful and patient was asymptomatic 4 months after surgery. Conclusion Myxoid liposarcoma is a rare tumor in head and neck and surgical excision with adequate margin is the treatment of choice. How to cite this article Mohiyuddin A, Raj S, Merchant S, Arun P.
