Areolar glands or Glands of Montgomery are sebaceous glands in the areola surrounding the nipple. The glands make oily secretions (lipoid fluid) to keep the areola and the nipple lubricated and protected. Volatile compounds in these secretions may also serve as an olfactory stimulus for newborn appetite.[1]
The portions of the gland visible on the skin's surface are called "Montgomery tubercles". The round bumps are found in the areola, and on the nipple itself. They can become exposed and raised when the nipple is stimulated. The skin over the surface opening is lubricated and tends to be smoother than the rest of the areola. The tubercles become more pronounced during pregnancy.
The number of glands can vary greatly, usually averaging from 4 to 28 per nipple.[2]
They are named after Dr. William Fetherstone Montgomery (1797–1859), an Irish obstetrician who first described them in 1837.[3][4]

- Mitochondrial DNA polymorphism in genes encoding ND1, COI and CYTB in canine malignant cancers.
- Slaska B1, Grzybowska-Szatkowska L, Nisztuk S, Surdyka M, Rozanska D.Author information 1Department of Biological Bases of Animal Production, University of Life Sciences in Lublin , Lublin , Poland .AbstractAbstract The aim of the study was to identify DNA changes in mitochondrial gene fragments: NADH dehydrogenase subunit 1 (ND1), cytochrome c oxidase subunit I (COI) and cytochrome b (CYTB) in tumor tissue, normal tissue and blood, and to define their association with the tumor type in dogs. Molecular analysis included 144 tests in total. A functional effect of the non-synonymous protein coding SNP was predicted. The presence of polymorphisms in all tested gene fragments in individual tissues of dogs was observed. Heteroplasmic changes were found in ND1 and CYTB in epithelioma glandulae sebacei and in CYTB in lymphoma centroblasticum. The results of in silico analysis show the impact of these alleles (COI: 507, ND1: 450, 216, CYTB: 748) on the functioning of proteins and thus their potential role in carcinogenesis. The possible harmful effects of changes in polypeptides in positions T193N, V98M, V118M and H196P were evaluated. It seems that polymorphisms occurring in cells can have a negative impact on functioning of proteins. This promotes disorders of the energy level in cells.

- Levator glandulae thyroideae, a fibromusculoglandular band with absence of pyramidal lobe and its innervation: a case report.
- Chaudhary P1, Singh Z, Khullar M, Arora K.Author information 1Associate Professor, Department of Anatomy, G.G.S. Medical College , Faridkot, Punjab, India .AbstractAmongst the endocrine glands, thyroid gland is well known for its developmental anomalies, which range from common to rare ones. The presence of levator glandulae thyroideae and its anatomical variations gain importance in the pathologies which are related to thyroid gland and their treatment modalities. Levator glandulae thyroideae is a fibromuscular band. If it is present, it is usually seen on the left side, to connect the pyramidal lobe of thyroid gland and the hyoid bone. But levator glandulae thyroideae which stretches from isthmus to the body of hyoid bone is rare and only very few cases have been reported in the medical literature. During a routine dissection of the thyroid gland in a 55 years old male cadaver, a Levator Glandulae Thyroideae (which was fibromusculoglandular in nature) was seen, with the absence of pyramidal lobe on the left side. It directly came from upper border of isthmus and went upto hyoid bone. It also had innervation from branches of external laryngeal nerve. This was also associated with absence of superior thyroid artery on the same side. The knowledge on various developmental anomalies of the gland and variations in neurovascular relations will help the surgeons in plan thyroid surgeries in a better and safe way.

- Mitochondrial D-loop mutations and polymorphisms are connected with canine malignant cancers.
- Slaska B1, Grzybowska-Szatkowska L, Surdyka M, Nisztuk S, Rozanska D, Rozanski P, Smiech A, Orzelski M.Author information 1Department of Biological Bases of Animal Production, University of Life Sciences in Lublin , Lublin , Poland .AbstractAbstract The aim of the conducted investigations was to identify differences in the D-loop nucleotide sequence between neoplastic tissue, normal tissue, and blood and to determine their correlation with the type of cancer in dogs. In 62.5% of the analyzed tumors of epithelial origin and 25% tumors of mesenchymal origin, substitution was detected within the D-loop sequence between the neoplastic tissue, normal tissue, and blood. Two mutations occurring in the carcinogenic process in position T15620C have been identified in epithelioma glandulae sebacei and carcinoma planoepithelialae keratodes. Blood and cancer heteroplasmy was diagnosed for carcinoma planoepithelialae keratodes and "Comedo" carcinoma. The results of the study indicate that polymorphic changes in the D-loop sequence promote carcinogenesis in dogs. Heteroplasmy diagnosed in blood and tumor cells and absence thereof in normal tissue may imply mtDNA recombination. High prevalence of mtDNA mutations in canine tumors may suggest mtDNA genetic instability, which is likely to play a role in carcinogenesis.
