Lymphangiomas are rare, congenital malformations of the lymphatic system which have a marked predilection for the head and neck. In this region, they most commonly occur on the dorsum of the tongue, followed by the lips, buccal mucosa, soft palate, and floor of the mouth. Lymphangiomas of the tongue are commonly present at birth; however, they may go unnoticed until after eruption of the dentition or even puberty. They may present as a defined mass or as macroglossia with impaired speech, difficulty in mastication, and, in extreme cases, airway obstruction. Clinically, lymphagiomas of the tongue are characterized by clusters of pebbly, vesicle-like nodules. A benign proliferation of lymphatic vessels is identified histologically. A classic case of a lymphangioma of the dorsal tongue is presented.

Primary uterine angiosarcoma with "rhabdoid morphology": A case report

Gandhi JS, Kamboj M, Gupta G, Seth N

Malays J Pathol, 2018 Aug;40(2):203-207.

PMID: 30173240

INTRODUCTION: Primary uterine angiosarcoma is a very rare tumour, with only 23 cases described till now. It is a malignant tumour with cells variably recapitulating the morphologic features of an endothelium and expressing immunohistochemical markers of endothelial cells. In general, it is a bulky neoplasm and frequently is at advance stage of disease at presentation. In general, patients with uterine angiosarcoma tend to have a poorer prognosis, mostly related to the aggressive nature and the metastatic potential of these tumours.

CASE REPORT: We report a rare case of primary uterine angiosarcoma with unusual rhabdoid morphology in a 41-year-old female, who underwent radical hysterectomy and died of disease after 4 months of treatment.

DISCUSSION: We described the differential diagnosis of primary angiosarcoma of the uterus that can pose a diagnostic challenge.

A 25-year-old Chinese woman presented with recurrent painless swelling over the left medial canthus region for 3 months and intranasal mass for an indeterminate duration. Initial incision biopsy of the mass was reported as nodular fasciitis but the lesion recurred 3 weeks later. Intraoperative findings during repeat biopsy showed a mass extending from the deep dermal tissue into the anterior orbit and polyp-like nasal mass. Histopathology findings were that of dermatofibrosarcoma protuberans (DFSP). The mass recurred 4 months later without orbital or intranasal recurrence. Wide excision biopsy under frozen section guidance was attempted however; clear surgical margins could not be achieved despite extensive resection. She was subsequently referred for adjuvant radiotherapy. We report an exceptionally rare case of local recurrence of DFSP in an unusual anatomic location. This case was surgically challenging in achieving negative margins, and thus neoadjuvant therapy may improve overall outcome to prevent local relapse.

Intratumour amyloidosis in Malaysians: an immunohistochemical study

Looi LM

Ann Acad Med Singap, 1986 Jan;15(1):52-6.

PMID: 3010797

Congo red screening of tumour material examined at the Department of Pathology, University of Malaya revealed intratumour deposits of amyloid in 12% of nasopharyngeal carcinomas, 66% of basal cell carcinomas, 100% of medullary carcinomas of the thyroid, 56% of islet cell tumours of the pancreas, 1 out of 16 carcinoids and 1 out of 100 thyroid adenomas. All the deposits were permanganate resistant and did not contain AA protein, indicating that what was encountered was not secondary amyloid. The deposits showed variable staining for immunoglobulin light chains and amyloid P component with a standard peroxidase antiperoxidase method. The possibility that intratumour amyloid has a neoplastic origin is discussed.

PMID: 8179566

This case represents a unique primary ovarian tumour consisting of malignant mucinous elements and granulosa-theca-cell elements, the histogenesis of which remains uncertain. It also underscores the need for thorough sampling of mucinous tumours in order to discover a possible coexisting, different neoplastic component.

Fulltext Evidence in support of potential applications of lipid peroxidation products in cancer treatment

Erejuwa OO, Sulaiman SA, Ab Wahab MS

Oxid Med Cell Longev, 2013;2013:931251.

PMID: 24369491 DOI: 10.1155/2013/931251

Cancer cells generate reactive oxygen species (ROS) resulting from mitochondrial dysfunction, stimulation of oncogenes, abnormal metabolism, and aggravated inflammatory activities. Available evidence also suggests that cancer cells depend on intrinsic ROS level for proliferation and survival. Both physiological and pathophysiological roles have been ascribed to ROS which cause lipid peroxidation. In spite of their injurious effects, the ROS and the resulting lipid peroxidation products could be beneficial in cancer treatment. This review presents research findings suggesting that ROS and the resulting lipid peroxidation products could be utilized to inhibit cancer growth or induce cancer cell death. It also underscores the potential of lipid peroxidation products to potentiate the antitumor effect of other anticancer agents. The review also highlights evidence demonstrating other potential applications of lipid peroxidation products in cancer treatment. These include the prospect of lipid peroxidation products as a diagnostic tool to predict the chances of cancer recurrence, to monitor treatment progress or how well cancer patients respond to therapy. Further and detailed research is required on how best to successfully, effectively, and selectively target cancer cells in humans using lipid peroxidation products. This may prove to be an important strategy to complement current treatment regimens for cancer patients.

An interesting case of isolated pancreatic teratoma: lessons to learn

Razman J, Azlanudin A, Eyad AJ, Zahiah M, Das S

Clin Ter, 2012 Nov;163(6):495-7.

PMID: 23306744

Mature cystic teratomas of the pancreas are extremely rare tumours encountered in day-to-day clinical practice. Only few cases have been reported to date involving all age groups. The management, diagnosis and evaluation of this tumor are questionable, with definitive diagnosis taking place intra-operatively. We hereby report the case in a 30 year-old-male who presented with newly diagnosed diabetes mellitus and during the follow up he was noted to have elevated liver enzymes clinically, he was asymptomatic. The computerized tomography revealed a retropancreatic mass and pushing the mesenteric veins anteriorly. The mass was hypodense in nature and there was presence of calcification. Although the patient was asymptomatic, the decision for resecting the mass was made in view of the size and possibility of malignancy. In conclusion, considering the size and approximity of the mass to the pancreas, Whipple procedure's is the most appropriate approach although the histological diagnosis has not been established preoperatively.

Malignant teratoma of the thyroid with predominantly neuroepithelial differentiation. Fine needle aspiration cytologic, histologic and immunocytochemical features of a case

Jayaram G, Cheah PL, Yip CH

Acta Cytol., 2000 May-Jun;44(3):375-9.

PMID: 10833994

BACKGROUND: Teratoma of the thyroid in adults is extremely rare, and most are malignant. Only nine cases have been adequately documented in the English-language literature, and there are no reports detailing the fine needle aspiration (FNA) cytologic characteristics.

CASE: A 32-year-old female presented with a left-sided nodular thyroid mass with left cervical lymphadenopathy. FNA cytology of the thyroid and lymph nodes was done. The cytologic and immunocytochemical features were that of a small round cell tumor with neuroepithelial (NE) differentiation, metastasizing to the cervical nodes. Microscopic study of the thyroidectomy specimen showed a tumor showing an NE pattern with occasional islands of squamous and cuboidal epithelium, leading to a diagnosis of malignant teratoma.

CONCLUSION: Knowledge of FNA cytologic features of rare but highly malignant lesions like thyroid teratomas allow early recognition so that suitable and possibly aggressive treatment protocols can be adopted in the hope of prolonging survival.
