【6】An Unexplained Hard Mass in the Thigh: A TCM Case Reflection Using the Yang He Tang Approach

Important Notice
This article is for educational purposes only and reflects one Traditional Chinese Medicine clinical case experience. It is not medical advice, diagnosis, treatment recommendation, or a guarantee of results. Any unexplained mass, especially one that is hard, large, poorly defined, growing, painful, warm, red, numb, or associated with functional changes, should be evaluated by a qualified medical professional to rule out conditions such as tumor, infection, blood clot, hematoma, or other serious disorders. Herbal medicine should be used only under the guidance of a qualified practitioner and should not delay necessary medical evaluation.( It is hereby clarified that the underlying intent behind all educational exchange cases published henceforth aligns with this principle.)

1. A Concerning Hard Mass in the Thigh
One Saturday in clinic, a woman in her late sixties, Ms. Lan, came to see me. She said, “Doctor, could you please take a look at my thigh? There is a very hard lump.”
Upon examination, the mass was located on the inner and anterior aspects of the upper-middle thigh. It was relatively large, approximately 12 cm by 18 cm. The texture was very firm, and the border was not clearly defined.
Because an unexplained hard mass must first raise concern for serious medical conditions, I did not treat it casually. I advised her to seek evaluation from Western medical surgery or an appropriate specialist.
The patient said she had already seen a Western medical doctor, and surgery had been recommended. However, she was not willing to proceed with surgery at that time and strongly wished to try Chinese herbal medicine. After careful discussion, I explained clearly that we could only proceed with close observation. If the mass did not soften or decrease, or if it became larger, painful, hot, red, or otherwise changed, she would need to return for further medical evaluation immediately.
2. TCM Pattern Differentiation
From a Traditional Chinese Medicine perspective, the mass had several notable features.
It was broad and diffuse, with an unclear border. The local area was not red, hot, or painful. There was no obvious pitting on pressure and no significant tenderness. The patient reported a numb sensation in the area. Her bowel and urinary functions were normal. Her tongue was pale-red with a slightly dusky tone, with a thin coating. Her pulse was wiry.
Based on these findings, I considered the TCM pattern of “yin-type swelling” or “yin ju.” This term does not correspond to one specific modern medical diagnosis. Rather, it is a traditional description for a type of swelling or mass that tends to be less red, less hot, less painful, slower in development, and associated with cold, stagnation, phlegm, and blood stasis patterns.
The main pattern differentiation in this case was cold stagnation, qi stagnation, phlegm accumulation, and blood stasis, with insufficient warming and transforming function of yang qi.
3. Treatment Principle and Herbal Strategy
The treatment principle was to warm yang, nourish blood, transform phlegm, move stagnation, activate circulation, and soften hardness.
The formula strategy was based on the classical idea of Yang He Tang, with modifications according to the patient’s presentation. The herbal direction included warming cold stagnation, supporting blood movement, transforming phlegm accumulation, and helping disperse hardness.
The herbs used in this case included Lu Jiao, Lu Jiao Shuang, Ma Huang, Shu Di Huang, Gui Zhi, Bai Jie Zi, Tu Bie Chong, Zao Jiao Ci, Huang Qi, Bai Zhi, Dang Gui Wei, Zhe Bei Mu, Gan Cao, and Chuan Xiong.
This formula is not a general recommendation for self-use. Some of these herbs are strong and may not be appropriate for everyone. Herbal treatment should be individualized based on constitution, medical history, current medications, examination findings, and professional assessment.
4. Clinical Observation
One week later, the patient returned for follow-up. She said happily, “Doctor, it has become softer and smaller.”
On examination, the mass appeared softer than before, and the size had decreased. This suggested that the TCM treatment direction may have matched her individual pattern. With continued caution and monitoring, I continued the same general therapeutic approach with adjustments.
Over approximately five weeks of follow-up, according to the clinical observation at that time, the thigh mass gradually reduced and eventually resolved.
5. Clinical Reflection
This case illustrates that Traditional Chinese Medicine does not treat only by a disease name. It pays close attention to the color, temperature, pain level, texture, border, pressure response, and the patient’s overall constitution, tongue, pulse, and systemic condition.
A “mass” may have very different underlying patterns. Some may show heat, some cold; some blood stasis, some phlegm accumulation; some may be related to infection, tumor, vascular conditions, lymphatic disorders, or other medical problems. Therefore, it is not appropriate to use one herbal formula for every lump or swelling.
The value of TCM lies in individualized pattern differentiation and whole-person assessment. However, for any unexplained large or hard mass, modern medical evaluation remains essential. Traditional treatment should not delay necessary diagnosis or urgent care.
