Parathyroid cysts (PCs) are rare lesions, located in the neck and anterior mediastinal region. The vast majority are non-functioning, presented as nodular cervical lesions. Large, non-functioning PCs can manifest with compressive symptoms of the surrounding tissues. Rarely, PCs produce excessive amounts of parathyroid hormone (PTH), resulting in primary hyperparathyroidism. We ...

Primary hyperparathyroidism is most commonly diagnosed in the setting of benign parathyroid adenoma(s). However, it can also rarely be caused by parathyroid malignancy and when it is, the clinical manifestations far supercede the presentation of benign parathyroid adenoma. We report a case of suspected benign parathyroid adenoma induced primary hyperparathyroidism ...

Epithelioid hemangioendothelioma (EHE) of the lung and pleura are rare tumors. Primary pleural EHE are associated with aggressive behavior and poor clinical outcome. Recent advances in EHE include the development of immunohistochemical markers of vascular differentiation, namely Fli-1, and the identification of a specific chromosomal translocation (t(1;3)(p36;q25)). We present a ...

Adenocarcinoma is the most common gastric tumour in dogs. Clinical signs and laboratory results are often non-specific, with histopathological examination of gastric biopsies being required to reach a definitive diagnosis. Use of cytology would potentially shorten the time to diagnosis and allow early interventional measures to be implemented. However, there ...

Balloon cell melanoma is a rare melanoma subtype, with only one previous case with dermatoscopy published. It is often non-pigmented, leading to diagnostic difficulty, and there is a tendency for lesions to be thick at diagnosis. We report a case of balloon cell melanoma on the forearm of a 61-year-old ...

In the last decade, the advent of biological targeted therapies has revolutionized the management of several types of cancer, especially in the realm of hematologic malignancies. One of these pathways, and the center of this review, is the phosphatidylinositol-3-kinase (PI3K) pathway. The PI3K pathway seems to play an important role ...

Metachromatic Leukodystrophy is a lysosomal storage disorder caused by Arylsulfatase A deficiency. Diagnosis is usually performed by measurement of enzymatic activity and/or characterization of the gene mutations. Here we describe a family case in which the determination of enzyme activity alone did not allow diagnosis of the pre-symptomatic sibling of ...

Despite advances in cancer diagnosis and therapy, metastatic melanoma remains untreatable, due to its notorious resistance to apoptosis, deeming traditional therapies obsolete. Deregulated PI3K/Akt signalling is a common oncogenic event enabling melanocyte transformation, and represents a significant and 'druggable' pathway in melanoma. Emerging data show that, the ability of cancer ...

For the fine-needle aspiration (FNA) diagnosis of melanoma recognition of characteristic morphologic features is key. In our practice we noted that cytoplasmic vacuoles in Romanowsky-stained FNA smears of melanoma appeared to be a frequent finding. To investigate this premise, we examined 36 consecutive melanoma FNA cases that had both adequate ...

Fine needle aspiration cytology (FNAC) of the thyroid is an established first-line test for thyroid lesions. Marginal vacuoles (MVs) have been associated with hyperactivity of the thyroid, but some studies have pointed towards their nonspecific status. To assess the presence of MVs in diffuse thyroid enlargements and evaluate the strength ...

Chordomas are rare, slow-growing malignant bone tumours arising from cellular remnants of the notochord. These tumours are locally invasive but have also a metastastic potential.Chordomas are characterized by the presence of physaliferous cells in a myxofibrillary stromal background. In cytological aspirates, these characteristic cells are usually absent, revealing only clusters ...

FNAC thyroid is more sensitive as well as specific in segregating neoplastic and non-neoplastic thyroid lesions. Identification of predominant cell pattern, cell morphology and background details in FNAC smears play an important role in categorisation of various thyroid lesions with accuracy. Marginal vacuoles (MVs) have been described as irregular cytoplasmic ...

Cerebral venous thrombosis (CVT) is an uncommon cause of stroke with diverse etiologies and varied clinical presentations. Because of variability in clinical presentation and neuroimaging, CVT remains a diagnostic challenge. Recently, some studies have highlighted the value of T2∗-weighted gradient-echo MRI (T2∗WI) in the diagnosis of CVT. We report the ...

Vestibular papillomatosis (VP) is a benign condition of the female genitalia that may be mistaken for condyloma acuminatum (genital warts). In contrast to condylomata, lesions of VP each grow from a distinct mucosal insertion; match the color of the surrounding mucosa; and are symmetrically distributed, limited to the inner labia ...

Armanni-Ebstein lesions were first described by Luciano Armanni, a pathologist at the University of Naples, during autopsy studies undertaken in 1872, as a unique vacuolar nephropathy associated with poorly controlled diabetes that involves selective renal epithelial cell glycogen accumulation. However, within the last two decades, a broader range of vacuolar ...

Inflammatory pseudotumours of the liver are extremely rare benign lesions. They were first described by Pack and Baker in 1953. They usually present with raised inflammatory markers and nonspecific abdominal symptoms. Most of these lesions are picked up incidentally on ultrasound scans. Diagnosis of these lesions poses a dilemma and ...
