A tale of recurrent secretory carcinoma of submandibular gland in an adolescent male: A rare presentation of a rare tumor.

Mammary analogue secretory carcinoma (MASC) is a rare salivary gland tumor which shares its histologic, immunohistochemical, and genetic features with the secretory carcinoma (SC) of breast. In this case report, we describe a case of MASC in a young adolescent male with swelling in the right angle of mandible which is a relatively rare site to present along with its correlation of cytological, histological, and immunohistochemical features. A 16-year-old male came with the complaint of swelling in the right angle of mandible since 2 years. Contrast-enhanced computed tomography (CECT) neck revealed differential diagnosis of nerve sheath tumor, pleomorphic adenoma, and adenoid cystic neoplasm was kept, and subsequently fine-needle aspiration cytology (FNAC) was done. FNAC was done in which differential diagnosis of myoepithelial neoplasm, acinic cell carcinoma, and SC was given. Surgical excision was done followed by histopathological examination. Immunohistochemistry panel was also applied, and final diagnosis of SC was rendered. SC has distinct cytological, histological, and immunohistochemical features which should be recognized by the pathologists for the appropriate management of the patient.

Calcifying Aponeurotic Fibroma of Leg Masquerading as Hemangioma in an Adolescent Male along with Review of Literature.

Calcifying aponeurotic fibroma (CAF) is a rare soft tissue tumor which falls under the WHO category of benign fibroblastic and myofibroblastic tumors. It typically occurs on the distal extremities (hands and foot) of children and adolescents. Other less common sites include wrists, ankles, trunk and rarely legs and arms. These tumors present as a painless soft tissue mass, arising in the subcutis, and are usually connected to tendons or aponeuroses. Computed tomography (CT) and magnetic resonance imaging (MRI) are the radiological investigations of choice; however, histopathology remains the diagnostic modality of choice for the diagnosis of CAF. We present a rare case of a 17-year-old boy who presented with a gradually progressive mass lesion on the leg which was later diagnosed as calcifying aponeurotic fibroma on histopathology.

Isolated intramuscular cysticercosis of the forearm masquerading as malignancy.

A woman in her mid-20s presented to an Indian tertiary care hospital with pain in her left forearm. Extensive initial investigations led to a suspected diagnosis of a peripheral nerve sheath tumour; however, the pathological investigation of the excised tumour mass revealed it to be a case of isolated intramuscular cysticercosis in the forearm. Treatment for cysticercosis was commenced and the patient made a full recovery. Isolated intramuscular cysticercosis without the involvement of other organs is a rare presentation and has only been reported in a handful of case reports. We suggest that isolated intramuscular cysticercosis be considered a differential diagnosis in patients with isolated pain in their muscles and with no other symptoms, in patients with a presentation of solitary swelling and in patients at risk of parasitic infection. In addition, we emphasise the importance of histopathological examination due to the varied presentation of cysts.

Ocular metastasis from renal malignancies - A comprehensive review.

The most common cause of intraocular mass is metastasis from other tumors. Renal malignancies, though rare, have a substantial number of cases with ocular metastasis, few of which were misdiagnosed. Many a times renal malignancies present with ocular manifestations before the primary diagnosis. Here in this article, we comprehensively reviewed 106 cases of ocular metastasis from renal malignancies published till date to the best of our knowledge. The eye is a rare site for distant metastasis because of the lack of a lymphatic system. The most common ocular structures to get involved in distant metastasis are the uveal tract, i.e., choroid, iris, and ciliary body. The most common renal tumor which metastasizes to eyes is renal cell carcinoma (RCC). RCC accounts for less than 2% of all ophthalmic metastases. Out of total 106 cases, the type of renal malignancy was known in 95 cases only, of which 92 had RCC, 1 Wilm's tumor, 1 rhabdoid tumor, and 1 medullary carcinoma. The age ranged widely from 2 weeks old to 81 years old. The male to female ratio was 3.4:1. In total, 67.4% of cases had a previous history of RCC, while the rest 32.6% primarily presented with ophthalmic manifestations first. Treatment modalities included enucleation of the eye, debulking surgery followed by radiotherapy and/or chemotherapy and/or immunotherapy.
