Papillary cystadenocarcinoma (PCC) is an uncommon malignant tumour of the salivary gland, sometimes involving the minor salivary gland. Previously this entity was classified as an atypical type of adenocarcinoma, malignant papillary cystadenoma, low-grade papillary adenocarcinoma or mucus producing adenopapillary carcinoma. PCC is a glandular tumour with an indolent biological behaviour characterised by cysts and papillary endophytic projections. We report two cases of PCC involving the minor salivary gland of the hard palate. Both the patients presented with a swelling in the palate with difficulty in chewing. MRI revealed an extensively destructive lesion involving hard palate, alveolar ridge and maxillary antrum. Clinical and radiological features suggested the malignant nature of the lesion. Histopathology of incisional biopsy revealed tumour proliferation in a multicystic pattern, with extensive papillary proliferation. Diverse and cellular cytomorphology, and cellular and nuclear pleomorphism with few mitotic figures were the prominent features. Both the lesions were confirmed as PCC.

A meticulous examination of the oral cavity is an essential part of the initial newborn assessment. The differential diagnosis can involve benign and self-limiting lesions to those lesions compromising quality of life. We present a clinical case of a newborn born with a purple, hard tumour on the hard palate that spontaneously regressed, being thus compatible with the case of a sucking blister.

The 73-year-old non-Hispanic, African-American man with a history of renal cell carcinoma (RCC), status post-nephrectomy receiving Lenvatinib, and metastatic disease, for which he also had received nivolumab for 13½ months. An itchy eruption appeared one month after the discontinuation of nivolumab and after the beginning of axitinib therapy. Physical examination revealed pink-violaceous scaly plaques, some with trailing scales on the anterior aspect of the trunk (Figure 1), a slight erosion on the hard palate, and hypopigmentation on the hands and legs.

Background: Obesity has been associated with human obstructive sleep apnoea and canine brachycephalic obstructive airway syndrome. The effect of body condition score (BCS) on structures of the oropharynx, nasopharynx and upper airway of the horse has not been investigated.
Objectives: To investigate the effect of BCS on tongue measurements, soft palate angle and basihyoid depth in horses.
