Patient discussion about axillary region

Q. A lump in my armpit Hi, Last week after the shower I found a small painful lump in my right groin. I went to see a doctor and he prescribed me some antibiotics. I’ve been taking it for 5 days and the lump is still there. I’m 31, usually healthy and work-out in the gym regularly, don’t smoke or use drugs and don’t take any medications. Is that dangerous? Should I go and see another doctor?

A. What you describe sounds like enlarged lymph node. The first diagnosis that’s suspected in such case is an infection that makes it painful. The antibiotics you take need several more days to act, so currently it doesn’t sound suspicious. If the lump persist, it’d be wise to consult you doctor

Q. I located a lump on the surface of my right underarm. I think I am showing some signs of breast cancer. I am 27 years old working lady. I think I am showing some signs of breast cancer. I located a lump on the surface of my right underarm. This lump is of a cherry size and does not pain at all. But I do have pain in my breast. I had my mammogram done which showed no lump and my doctor says that there is nothing to worry and she has given me some medicines. I want to know that if everything is normal then how come these lumps came.

A. there are ways to diagnose if lumps are breast cancer or not. a lump under the forearm can be a sign of an advanced stage of cancer, but it can also mean some kind of viral infection that caused a lymph node to swell up. so if a doctor told you it's fine- he probably checked it out, and it's fine. if you still anxious - go get a second opinion.

Having contextualized muscular variations in the axillary region and their clinical relevance, we present an anatomical variation of this type, which is of interest for surgeons and anatomists considering its implications during surgery or dissection of a cadaver.
[6] As regards to the site of FNAC, cervical region (70%) was the commonest site of lymphadenopathy followed by axillary region (15%) as observed by Ahamad SS et al, [7] Hirachand et al [8] and Agarwal et al.
In breast cancer patients with pathologic lymph nodes in the axilla, conditions such as the presence of uncommonly propagated LAP outside the axillary region, significant mediastinal involvement, or detection of parenchymal pathology accompanied by clinic tuberculosis or tuberculous-suspected parenchymal pathology could be helpful to determine the sampling group.
Physical examination is the mainstay in the diagnosis of AWS, and examination of the axillary region should not be ignored in patients with shoulder pain and limited ROM.
In both groups, a 22-gauge, 5cm block needle was entered to the axillary region with visualisation of the whole needle on ultrasound and 20ml local anaesthetic of 0.5% bupivacaine was injected.
(a) At surgery, the patient's arm is positioned at 80[degrees] of abduction and neutral flexion, extension, and rotation due to make a 4 cm long skin incision as a utility port along the mid-axillary line between the fifth and sixth costal spaces in the axillary region (n), which was directly located on the T5/6 disc level.
In March 2016, a new biopsy from a residual nodule lesion of the right axillary region revealed an atrophic epidermis with an infiltrate composed by foamy histiocytic granuloma with giant vacuoles occupying the entire extend of the dermis.
Further examination on the contrast-enhanced CT and the presence of unilateral multiple circumscribed dense nodes, some of which have large and dotted calcifications, might suggest tuberculous lymphadenitis in axillary region. Early diagnosis and treatment of tuberculosis decrease the opportunities for the spread of the disease in the community.
Inflammatory involvement in the left axillary region was also present.
Many factors may explain the discrepancy between the false negative rate of SLNB and the overt clinical axillary failure post negative SLNB; the more liberal use of systemic adjuvant therapy which sterilizes and downstages positive lymph nodes,19 the rather short median follow - up period of some published studies,20,21 the possibility of incorporating the lower axillary region into the radiation field directed at the breast, and probably the ever - improving sentinel lymph node identification rate in recent studies.22
