Is it possible in a  breast cancer to involve chest wall without involving pectoralis major. If so in which type of breast cancer

If you are talking about the deep tissues beneath the pectoralis major, it would be very unusual.  It would almost require that the breast cancer cells got there through the bloodstream, rather than by local invasion, in which case you would have metastatic disease.  Pectoralis major involvement is almost always due to local invasion and tissue destruction.  That is more common with adenocarcinoma than with lobular carcinoma.  Hope this helps.
